Problems with Perl's in-memory buffers

Sat, 15 Sep 2012 19:48:00 -0400

Perl does lots of things that make life easier, from postfix conditional and looping constructs, to DWIM-infused language design. One of interesting things I discovered when learning to open a file was that Perl can treat a scalar as an in-memory file:

my $string = "many\nlines\nof\ntext";
open my $in, '<', \$string;
while (<$in>) { print }
