getvalue's the right way in if you're supporting accesses to partial
arrays, for example, although there ought to be simpler ways of
e.g. simply retrieving a pamraeter expression as a string, as is done in
other modules -- although most other modules make more limited use of
parameters, and the one that doesnt, zsh/parameter, is mostly there to
define new parameters so isn't much use as a reference.  What
zsh/parameter might help with is showing you how to access functions
etc. since some of the parameters give you back doors for manipluating
them.

Yes, however there's no major penalty in exporting other functions.  We
never sat down and defined a complete API, so if you need to mark
another function as mod_export that's OK.

In practice, mod_export may be largely redundant: of the systems I've
encountered, only AIX actually needs the functions marking specially for
the linker, which is what mod_export is for.
