No, that's no good.  The whole point of calling it zparseOPTS is that the
things it is parsing are *optional*.  It returns nonzero only for things
that are real mistakes.

} +zparseopts -D -E 'g:=glob'
                    ^       ^			Why the quotes?
} +(( $#glob )) || glob=( -g '*(^/)' )

You could use 

	: ${(A)=glob:=-g '*(^/)'}

instead.

What I can't decide is whether I like the behavior of emptying the array
when no matching option is found.  E.g. sometimes I think I'd like to be
able to say

	glob=(-g '*(^/)')
	zparseopts -D -E g:=glob

and have $glob be unchanged unless a -g really was given.  Then I think
about it some more and decide maybe not.  Then I think about it some more
and ...
