I was just typing this up but stevan said it better (my first reply
was from my phone, not easy to type Perl on the G1).
This is exactly the solution I was recommending because it eliminates
the action-at-a-distance issues that Piotr's solution will bring up.
Using method modifiers will get you there, but can (will probably)
lead to a maintenance nightmare down the road. This way your validate
method expressly says what is going on so anybody coming in can read
the code and understand what is happening.
