Hi,

Is there a portable way to obtain a pointer to a member function and 
invoke it with the this reference? I seem to recall some discussion 
about this on the NG in the past, but can't find the thread now.

If you know both at compile time:

auto func = &object.func;

This will create a delegate with the this pointer and the function 
pointer. If you want to build it manually you can do that also:

alias void delegate() func_t;

func_t func;
func.funcptr = GetFunctionPointer();
func.ptr = object;
