Learning from Bad Code
I’ve written before about Linux Format’s habit of sharing badly written Perl code. I thought things were improving, but in the new edition (November 2012, issue 163) they’re back to their old tricks.

So Time::Piece has been in the Perl core since 5.9.5. I’m running Perl 5.14.2 but I don’t have Time::Piece installed. After ten minutes or so of head-scratching it came to me.
