Thanks for the work-around.

If this is not a compatibility or historical practice issue, I'd like to
suggest that the commands "local", "typeset", etc. all look like they are
used to declare the "type" of a variable.  As such, it seems that
"exportable" is a type attribute and that this attribute should be
associated with a variable for the remainder of its lifetime (or until
another typeset).  This could be implemented internally in zsh with a
tri-state flag: +x for exportable, -x for local, and ?x for "use the
current state of the allexport option".  If the export semantics in zsh can
be changed (and the maintainers are willing), I'll try to submit patches.
(But I don't want to do this if the current semantics are required by, for
example, ksh.)
