in reply to Difference between 'use warnings' and '-w' switch

this is the full line from that module:

my $size = do { local $^W; -f $local && -s _ };

note, he locally turns off the warnings , (old style -w/$^W warnings);


This is not a Signature...

    Thanks - actually the line in my version (2.70) is:

    $ftp->_ALLO(-s _) if -f $loc;

    And since there is no code to initialise $loc before this line, it will always produce a warning. It looks like this has been fixed in later versions (I checked 2.75 from CPAN) - it has been changed to the line you describe (note $local not $loc).

    Thanks.
