To clarify, what I meant was something like "I like it, but reality
does not seem to permit it now".

Ah, our emails crossed.  I would rather that tests that affect the
state be marked as such, nothing more.  The "always return to $TRASH"
rule is a lot stronger than that, unfortunately.  What I really liked
about your suggestion is that the "tests must start and end in $TRASH"
rule could be checked with very little effort.  Unfortunately, as the
list of scripts illustrates, that rule doesn't describe what our
current tests do.
