The reference to it is blessed # and handles methods. This gets round the Perl # "dereferencing bypasses tying" bug. Dereferencing # will always go to the tied proxy. $hiddens{$methprox} = $object; return $methprox; }

[atcroft]: .oO(It is a well-known, well-tried module that has probably encountered more corner-cases and oddities than the average mortal programmer can imagine when trying to roll their own...)

[james28909]: im just finding out that july and august have 31 days?

[atcroft]: james28909: Make both hands into fists, place them together (with thumbs concealed), and every knuckle is a month (starting with Jan.) has 31 days, every dip (between knuckles) does not....

[james28909]: i know but scroll through your calendar on your computer.

[atcroft]: .oO(Sorry, I probably should have said take two normal hands....)
