Depends on order of evaluation. :-)

Suppose I have the follwing; assume -Y is the expanding form of -X (mnemonic
is "why" :-) --

    compctl -K somefunc -Y '$somevar' somecommand

    somefunc() {
	reply=(some list of things)
	somevar="Some list of things means something"
    }

Now as long as "somefunc" runs before -Y performs its expansion, the value
of "somevar" is what "somefunc" wanted it to be.  This order of evaluation
ought to be possible, because the results of the function are needed before
zsh can even decide whether to print the explanation.
