warn

warn msg

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.
