I'm not sure that's correct. Might just be a runtime warning, with
$foo set to 0. Or a compile time error or warning, as we do know at
compile time what the behaviour of the int class is, and would likely
do this with some constant twiddling during the compile phase.
Dynamic assignment, like:
$foo = $bar;
would likely throw an exception at runtime, since the type mismatch
can't be safely inferred at compile time.
