$var = 6.3;
$a = (int) $var;

Or $b = (bool) "1";

This is usual code and it could be wanted to losse information on casting. Triggering errors for
that would be extremely annoying.

That's bad to read, destroys the possibility to integrate method overloading one day in the
future, and it is telling the wrong story.

If I have "function moo(int $var)" it shows that the method expects an integer.
If I have "function moo((int) $var)" it looks like: Give me whatever you want and I cast
it into an integer.
