Right, I think either would be good.

You didn't seem to have replied on that code snippet I provided before.
I assume, that inconsistency in BASH_SUBSHELL inside {...} invoked
directly and invoked inside EXIT trap, should be fixed one way or

I don't mean to be picking on these corner cases but I'm of curious mind
and thought I should raise it, when stumbled across. If nothing else,
somebody might find this thread useful while searching for answers.
