YAPH:
Actually, the first constructs gets read and interpreted by both shell and
perl. However, Perl doesn't execute it because of the "if 0" part, which
the shell, in turn, never reads because of the "exec" within the eval'd
string. It's actually pretty smart, but unnecessary since there easier
ways.
