That is why I suggested, in addition to the above, a syntax like:
function (Foo | NULL) foo($something) {
to be able to specify where a function can return more than one type.
The 'extra' types/values are nearly always either NULL or FALSE.
I agree that being able to specify as types: array, scalar, int, string, ...
would be useful for a compiler but prob have little value for Zend - other than
documentation/reflection.
