The Delphi VCL had a (has a) fancy function MakeObjectInstance which gives a flat function address that maps nicely to an object method.

Very fancy, just the kind of thing SWIG needs right now so that object wrappers around scripting functions can accept callbacks from routines that don't provide cookies.

Anyway; fpc comes into it because if MakeObjectInstance or the like works cross all the FPC platforms then we have a nifty cross-platform callback wrapper type system thing.

So if there is one I was hoping you wouldn't mind donating that bit to swig (www.swig.org)
