That solution is not particularly useful.  Consider something of the form

    if test ...
    then zmodload zsh/mathfunc
    fi

If you can't execute the conditional because of -n, how do you know that
it's safe to execute the zmodload?

IMO you've identified a deeper problem, which is that no module should be
allowed to alter the syntax accepted by the parser.  Conversely, if the
parser is able to cope with the syntax in the absence of the module, then
`zsh -n' has no business complaining about the semantics.

In this example:

> /usr/bin/vux:766: unknown function: int

`zsh -n' should simply accept that `int' IS a function, and should not try
to look it up.

In this case:

> /usr/bin/vux:784: bad math expression: operator expected at `h'

I can't give an opinion, "bad math expression" is too generic an error.
