JayBonci,
If you want to see it blow up you will have to do: 
BEGIN {
    while( calldepth < 5 ) {
        last;
    }
}

From perldoc perlmod
A BEGIN subroutine is executed as soon as possible, that is, the moment it is completely defined, even before the rest of the containing file is parsed.

You have put it into an infinite loop - never giving it a chance to throw the error.

Cheers - L~R
