Seems there's always something new to learn. Old, but interesting news I just found out.
Pre perl 5.8, one would use IO::String to treat a string like a file. With perl 5.8, one can do this using native open:
my $string = "Foo\nBar\nBaz";
open(my $fh, '<', \$string) or die "DOH: $!";
my $line1 = <$fh>;
my $line2 = <$fh>;
## $/ is of course obeyed ....
Next thing you know, there will be a musical genre named grunge ....
