in reply to Lexicals in if() scope gotcha!

Yikes! I've used the if ( my $foo = ... structure here and there in my code under the assumption that it would be scoped so as to DWIM; I'll have to keep my eye out for this...

Update: On second thought, this is less of a problem than it seemed at first; all of those uses are within subroutine blocks that will ensure the referenced values don't stick around forever.

Careful with your wording, the variable does go out of "scope" at the end of the "if" block, but the object refrenced by that variable refrences does not neccessarily get garbage collected.

(As opposed to old ANSI C, where the variable itself was still in scope ... oy, those days sucked.)
