Globbing in a function (was Re: globbing for links in pathnames)

	i have a function that i use to link executables from where i
normally install them to (usually /opt/wherever) to /usr/local/bin.
i was trying to rewrite it using this sort of format (rather than
invoking find, as i was doing before), but am running afoul of something
that i can't quite figure out.  the i've hacked out some stuff at the
beginning (to allow me to pass it options) for the sake of clarity; the 
interesting part is this:

(astaroth)~/.zfunc: BINLIST=(*(*)) ; echo $BINLIST ; unset BINLIST
binlink cwhois gpid mck newm newterm nobrs perf xbuffy xt xtitle
(astaroth)~/.zfunc: which binlink
binlink () {
        BINLIST=($1(*)) eval 'for BIN in ${=BINLIST} ; do 
      ln -s ${BIN} /usr/local/bin ;
(astaroth)~/.zfunc: binlink \*                                    
zsh: no matches found: *(*)

	putting an echo in at the end confirms that BINLIST in
the function is, when binlink is given an escaped asterisk as
its argument, being set to (*(*)); since parameter expansion
occurs before filename generation, why doesn't setting BINLIST
to that value in the function do the same thing that it does
from the command line?
