[fpc-pascal] Adding method dynamically to a class

[Jorge Aldo G. de F. Junior]

Use event properties (Properties to a procedural type)

Adding completely free methods to a class makes no sense.

By free i mean a method that has no clear signature (parameters and
result type) because calling them will be a nightmare (You will have
to do the compiler work and build your own parameter passing and
return type system).

This is usually done in interpreters but what you describe doesnt
sound like a interpreter.
