This seems a long way around the houses, is difficult to 
understand, and the result is a delegate with a frame pointer for 
the main function, which then has a nested function

void anon(int v) { a.bar(v); }

which somehow does not feel right, and if the compiler isn't 
clever, seems like another level of indirection.

Syntax like this (changed my mind ;=)) would be nice:

void delegate(int) dg = &a.bar;

I'm not particularly looking for a way of doing it at this 
moment, just whether it's something that could be done in the 
future.
