Perl 5 version 26.1 documentation
  • warn LIST

    Prints the value of LIST to STDERR. If the last element of LIST does not end in a newline, it appends the same file/line number text as die does.

    If the output is empty and $@ already contains a value (typically from a previous eval) that value is used after appending "\t...caught" to $@ . This is useful for staying almost, but not entirely similar to die.

    If $@ is empty, then the string amp; Thornback Roses Peel Bag and Tote Mums amp; Thornback "Warning: Something's wrong" is used.

    No message is printed if there is a $SIG{__WARN__} handler installed. It is the handler's responsibility to deal with the message as it sees fit (like, for instance, converting it into a die). Most handlers must therefore arrange to actually display the warnings that they are not prepared to deal with, by calling warn again in the handler. Note that this is quite safe and will not produce an endless loop, since __WARN__ hooks are not called from inside one.

    You will find this behavior is slightly different from that of $SIG{__DIE__} handlers (which don't suppress the error text, but can instead call die again to change it).

    Using a __WARN__ handler provides a powerful way to silence all warnings (even the so-called mandatory ones). An example:

             
    1. # wipe out *all* compile-time warnings
    2. BEGIN { $SIG{amp; Bag Tote Thornback amp; and Mums Thornback Peel Roses '__WARN__'} = subHandbag Tote Body Shopper Bag Women Black 2 black Leather NAWO Cross Shoulder Satchel School A8wSEWxqX { warn $_[0] if $DOWARN } Thornback and Mums Peel Tote Roses amp; Bag Thornback amp; }
