TransformCallableDefinitions

Added by Avishay Lavie

Scans the AST for callable definitions and converts them to class definitions which inherit from System.MulticastDelegate, and adds the definition of the Invoke and BeginInvoke methods. These are later filled in by the CLR.

That is, if the code before the step looks like this:

callable MyCallable(arg as int) as bool

It will be transformed to this:

class MyCallable(MulticastDelegate):
	def Invoke(arg as int) as bool:
		pass
 
	def BeginInvoke(arg as int, state as object, callaback as AsyncCallback):
 		pass  

and so on.
