ugh! it almost works :)  The issue is with lazy args and string/array 
literals.

If you do this:

call(true, &bob, "hello");

The compiler complains because it can't create a delegate function that 
returns a char[5u].  Functions cannot return a static array, so this seems 
rather silly (i.e. if you are lazily evaluating a string constant, there is 
no penalty for returning a char[] instead of a char[5u]).  I'm going to file 
it as a bug, but if this gets fixed, everything will be good!
