treating a string like a file

[ #30196 ]
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 ....
