Aye, I have fought with it before and never made a good solution.
The problem is that b can change at runtime, so it has no way of
knowing for sure which object it should use at compile time. It
does work easily if you use it as a runtime delegate though,
without being a template at all, or a type template like this:
import std.traits;
void call(T)(T t) if(isCallable!T) { t(); }
then
call(&foo) and so on should all work.
The other side of this problem is how can I cheat the
templating system so it would accept these kind of expressions?
I don't know any more though :( maybe someone else has some good
tricks.
