A slight tangent, but *if* this sort of syntax is adopted we need to think what
will happen when someone puts a class name in there instead of a basic type.

I would suggest that it be a compile error of some sort if the 'type' is
anything other than int, float, .... The only one that may make sense is

    function foo((array) $bar)

If $bar is not an array it would make an array containing one element with value $bar.
