Gosh!
Let's document it! Would it go in perlvar or perlsyn?
It's already documented, in perlvar/Technical Note on the Syntax of Variable Names

Odd. I always though that you could do that. Maybe it was just an
assumption I made without understanding. I've used %_ in one liners to
remove duplicates and other such fun.

We have been discussing how to pass data to Tk callbacks.
In particular Entry widget validation routines.
There are a number of items that they _might_ be interested in
