Good: you added a pair of parentheses.  Bad: one fell short.

If I assigned this value to func, then called it, I would have
to say:
	(*func)()
The type that this returns is short.  (Short int, more formally.)
Therefore, I'd have to declare func: short int (*func)() and cast
this (short int (*)()) 0.

Doug already said this, but without explanation.
