Ask the right questions to secure the right Cecil (programming language) talent among an increasingly shrinking pool of talent.
Cecil is a purely object-oriented programming language that was developed in the early 1990s at the University of Washington. It is noted for its flexible and efficient dynamic dispatch mechanism, which supports multimethods and subtype polymorphism. Cecil also includes mechanisms for safe type inference, delegation-based inheritance, separate implementation and type hierarchies, garbage collection support, multiple return values among others. The design philosophy behind Cecil was to create a language that would provide advanced features needed by sophisticated software systems while still being simple enough to be easily learned and used by novice programmers. The creators of Cecil aimed to combine the best elements from several other languages including C++, Smalltalk, Modula-3 etc., resulting in an expressive yet efficient programming tool. However it's worth noting that despite its innovative features at the time of development; today it's not widely used or known outside academic circles due to emergence of more popular languages with similar capabilities such as Python or Ruby.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
Cecil does not have built-in exception handling. However, you can implement your own exception handling mechanism using conditionals and method calls.
Static typing checks the types at compile-time, while dynamic typing checks the types at runtime. Cecil supports dynamic typing.
Delegation in Cecil is a mechanism by which an object can delegate some of its responsibilities to another object.
In Cecil, a method is defined using the 'method' keyword, followed by the method name, parameters, and the method body enclosed in curly braces.
Cecil includes features such as dynamic typing, multiple dispatch, a classless object model, delegation, and a flexible static scope rule for names.
Past experience with similar projects can be a big advantage. It means the candidate will be able to hit the ground running and will likely require less training.
Debugging is an essential part of programming. A good candidate should have effective strategies for debugging their code in Cecil.
While the focus is on Cecil, having knowledge of other languages can be beneficial. It indicates a broader understanding of programming and can be useful in certain projects.
The field of programming is constantly evolving. A good candidate should stay updated with the latest features and updates of the language.
Problem-solving is a key skill in programming. The candidate should be able to demonstrate their ability to use Cecil to solve complex problems.
A thorough understanding of Cecil is crucial for the role. The candidate should be able to demonstrate their proficiency in the language, and how they have used it in past projects.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
In a class-based model, objects are instances of classes. In a classless model, like Cecil's, there are only objects, and they can have their own individual behavior.
In Cecil, you can create an object by calling a constructor method, which returns a new object.
Advantages of Cecil include its support for dynamic typing, multiple dispatch, and a classless object model, which can make it more flexible and expressive than some other languages.
Cecil does not support inheritance in the traditional sense. Instead, it uses a prototype-based model where objects can delegate responsibilities to other objects.
Multiple dispatch in Cecil allows a method to be selected based on the runtime types of all its arguments, not just the receiver.
The candidate should demonstrate strong knowledge of Cecil's object-oriented, prototype-based model, good problem-solving abilities using the language, and familiarity with its garbage collection system. Red flags would include difficulty explaining concepts or applying them practically during coding tasks.

Designing a large-scale system in Cecil would involve careful planning of the object model, efficient use of multiple dispatch, and good use of delegation to manage complexity.
Single dispatch selects a method based on the runtime type of the receiver. Multiple dispatch, supported by Cecil, selects a method based on the runtime types of all arguments.
Optimizing a Cecil program for performance could involve techniques such as avoiding unnecessary object creation, using efficient data structures, and minimizing I/O operations.
The static scope rule in Cecil determines how names are resolved. It allows a name to refer to the nearest enclosing definition of that name.
Polymorphism in Cecil can be achieved through multiple dispatch, which allows a method to be selected based on the runtime types of all its arguments.
