Um, same thing as the CLEANUP subroutine; I apparently skimmed over
that.

Or variables Embperl doesn't realize are not imported.
Incidentally, I'm realizing that, if one were to add this, someone else
would likely want a variable %LEAVEDIRTY, for those few instances where
they were wanting something retained. Not that I need this, now that
I've come to terms with adding all kinds of stuff to %CLEANUP.

According to the description of what gets cleaned automatically, %modify
should be cleaned, because it's set in code in the webpage itself. But
it isn't being cleaned, unless we explicitly place it in %CLEANUP. As I
mentioned, I hadn't actually turned that logging on to look at what is
being cleaned. As it happens, Embperl is actually not trying to delete
the variable created in the above assignment at all - I'm guessing this
is due to that not matching the regex you have for 'what is a variable
assignment'.
