% | Parameter Parsing:
% |
% | A single parameter consists of a type and optional of a variable name.
% | If the type contains a "const ... &" pair, it is removed. If the
% | the type is similar to the class that is currently declared, it is
% | also removed. (In that case it might result in an empty parameter
% | if no variable name is given. Then, a dummy "#" is printed instead.
% |
% | The return type of a method or function has no `variable name', so
