I meant it more in the sense of "typeset is a reserved word". I know
that's only true to a limited extent and a future POSIX standardisation
of local would likely only cover functionality that works as a builtin.
I don't really have a strong opinion but would like to see the work
finished off and pushed.

I can understand that, its never easy to name these things.

I'd be fine with that too if you prefer. If you think you might want to
change how it is controlled later, an internal macro would make that
easier. But I'm, not sure backward compatibility concerns would ever
allow that anyway.
