Hmmm, 5.6.1 doesn't like local STDIN = $in; or local STDOUT = $out;.

that's because it's missing the sigil... local *STDIN = $in; or local *STDOUT = $out;

Is that a 5.8 feature? I've never seen that construct before. It'd be nice to have, though!

this is a standard feature (assuming the syntax is correct.) the first one will fail under 5.008 with the same errors. my correction should work fine under any recent perl.
