\zork() is not exactly a "constant", but it is an expression of type struct
\foo. However, it is *not* an lvalue so you cannot take its address.

What I intended to say: a function return value behaves as a constant;
once the value is known, you cannot suddenly decide to change it,
it isn't (a) variable, so it's meaningless to take its address.

Shorter:

	(i ? func1 : func2)().mids;
