Ruby methods can have symbols in its names that are not allowed as part of Python method names, for example !, ?, or =, so we cannot simply define Python methods and expose them to Ruby by the same name.
For defining the Ruby method name of a function, as well as argument number checking, Ruby type coercion and unwrapping of Ruby objects to their Python equivalents, we use decorators defined on ClassDef. When the ObjectSpace initializes, it builds all Ruby classes from their respective ClassDef objects. For each method in an implementation class that has a ClassDef decorator, a wrapper method is generated and exposed to Ruby. These wrappers define the name of the Ruby method, coerce Ruby arguments, and unwrap them for the Python method.
