in reply to Perl Idioms Explained - my $string = do { local $/; <FILEHANDLE> };

What about the 'idiom' my $data = do{local(@ARGV,$/)='file.txt';<>}

    Check here (tye solution) for why this may cause problems in some code.

    Of course, you could shorten his solution slightly:

    my $data= do { local( *ARGV, $/ ) = [ $filename ]; <> };

    Globs are such fun. Hope this helps.
