I was talking about zsh/mathfunc, too.

That's what I was going to suggest, even to the creation of Functions/Math/.

} How do I shield zmathfunc against callers that unsetopt functionargzero?

Sticky emulation would do it for you.  E.g.

    emulate zsh -c 'autoload -U zmathfunc'

Or examine $funcstack[1] instead of $0 (with localoptions noksharrays),
although that introduces a dependence on zsh/parameter.

} I guess I'll have to drop the the multifuncdef usage altogether?

See for example zmv, zcp, zln.

Although it seems an oversight that you can't combine -u and -M for the
functions command.

} +Autoloading tt(zmathfunc) defines the three mathematical functions

You do have to both autoload it and run it, like e.g. "colors".  Given
that, why not have zmathfunc perform "zmodload zsh/mathfunc" too?

Ehh, I'm not sure it's the job of any module's doc to explain what it
does NOT define, much less to cross-reference zshcontrib.
