i found the culprit, but it's like finding out that a butterfly
burned down your house. i still don't see how it's possible.
when i distill it, of course, the problem vanishes. but see

as is, the functions that follow (top-level 'sub xyz {}') get
screwy. code disappears.
replace "and" with "&&" and all is well. boggles my mind.

with 'and' *{$My::Debacle::{handler}}{CODE} doesn't exist.
i've got a similar snag in a different module, now, where defined
subs are disappearing. but i can't trace it to a stray 'and'
here... must be something deeper?
