### 3.2.192 warn

    warn LIST

This function produces a message on `STDERR` just like die, but doesn't try to exit or throw an exception. For example:

    warn "Debug enabled" if $debug;

If the message supplied is null, the message "Something's wrong" is used. As with die, a message not ending with a newline will have file and line number information automatically appended. The warn operator is unrelated to the -w switch.
