I think what Mike may be alluding to is that there is no name for the
stack frame pointer you can use. There is no 'this' pointer that you
can get at (even though it can be passed).
Also note that lambdas are not necessarily delegates, they could be
straight function pointers if they don't need a context:
void main()
{
int a;
pragma(msg, typeof((int b) => b * 2)); // int function(int b) pure
nothrow @nogc @safe
pragma(msg, typeof(() => a * 2)); // int delegate() pure nothrow
@nogc @safe
}
Yes, but then this = null. I matters not for my use case.
'this' is not null in either case. There is no 'this'.
There is probably a way to get the stack pointer. Take a look at the
code in std.functional.toDelegate.
