It seems odd to me to not support the aliases. Since I can do this:

   $foo =3D (integer)$bar;

I would expect to be able to do this:

   function foo(integer $param) {}

Also, do int, float, and numeric accept numbers in octal, hex, scientific n=
otation, etc.? I don=92t believe there are any examples in the RFC that int=
entionally or accidentally show what happens with, say, 0x2f as a value.
