Just for the sake of asking, why isn't it doable?



Well, revise that - it's doable, just a little tricky. Ideally, you just want to be able to go:

Local SomeFun(x)=obj.SomeMethod

SomeFun( 10 )

However, to implement this, 'SomeFun' needs to store 64 bits worth of info: a pointer to the 'obj', and a pointer to the 'SomeMethod', as 'SomeMethod' will likely need 'obj' (it's 'Self') - ie: the SomeFun(10) call is really obj.SomeFun(10).

This of course totally messes up 'normal' function calls, so you get into the territory of having to invent a new construct for 'method pointers'. These are commonly called 'delegates' in other languages.

Personally, I'd much rather see function pointers and delegates unified, but am yet to think of a way to do it 'nicely'. Its one of many things I will likely take another look at one day.
