in reply to IO::MultiHandle - Operate on multiple file handles as one

Did you test this? The following won't work: $fh->$AUTOLOAD( @args ) for my $fh @$self;
Perl hasn't seen the my when it sees the first mention of $fh so that one refers to the global variable of that name. Either declare the variable on a line by itself or use $_. $_->$AUTOLOAD(@args) for @$self;

Makeshifts last the longest.
