} I don't know. Is it necessary?
Without it, starting from an unset TZ, doing
torch% TZ=UTC strftime ...
results in TZ remaining set to UTC after strftime completes. With the
pm->level bump, TZ is back to unset again after strftime completes.
} The code in params.c that deals with
} locallevel suggests it shouldn't be.
If I skip the createparam() [necessary for PM_EXPORT] and instead just
setsparam(), then the parameter is properly removed from scope as I
would expect, but of course then strptime() doesn't work as desired.
So it has something to do with export?
I briefly considered adding an ASSPM_EXPORTED flag and changing the
behavior of assignstrvalue() in params.c, but decided against it.
