I totally agree with this. I can understand any of the following:
1) function f(int $a) { } == f( (int) $a); -- with NO notices
2) function f(int $a) {} means $a must be exactly type int -- or
recoverable error is thrown
3) current behavior (no scalar type hints)
But a new set of rules that require a 23x7 table to describe what's
going on ... not a big fan.
