Re^2: overloading ">>" generates warning?

what I'm trying to do is a file IO similar to IO::All' s, but only for files. It also uses this syntax, but don't generate any warnings. I didn't get how Ingy did that thing without a warning :(

Use the source, Luke! Have you looked at the source code? :-) `my $old_warn_handler = $SIG{__WARN__}; $SIG{__WARN__} = sub { if ($_[0] !~ /^Useless use of .+ $.+$ in void context/) { goto &$old_warn_handler if $old_warn_handler; warn(@_); } };` [download] It looks like he basically turned off that warning globally. the lowliest monk	[reply] [d/l]
