Bear in mind the original brief: On Mon, 2011-05-30 at 11:40 +0100, Leo Lapworth wrote: > I'm working on http://learn.perl.org/ and I'd like to have a few > rotating examples of what can be done with Perl on the home page. > [...] > one liners are fine as long as it is simple to see what they do. So these aren't lessons - they're standalone code samples. If it needs explaining it's probably too complicated. The Config::Any version of the read is: use Config::Any; my $config = Config::Any->load_files( { files => \@files } ); That's immediately readable and understandable, and it will load a config file (or files) written in almost any standard config-file format, rather than just key=val files. It doesn't teach people about all the raw Perl stuff your example uses, but as a standalone "ooh, look how easy it is to get stuff done in Perl" it's probably more suitable for the target audience and intended use-case.
