`perldoc perlvar`
$! If used in a numeric context, yields the current
value of errno, with all the usual caveats. (This
means that you shouldn't depend on the value of $!
to be anything in particular unless you've gotten
a specific error return indicating a system
error.) If used in a string context, yields the
corresponding system error string.
Note the parenthetical.

Don't print $! unless you've actually gotten a system error, such as from
open().
