} 	yes--because i need to start cut&pasting my functions rather
} than typing them in.  that should be -n, not -x.

That won't work either (and my remark about "unless there happens to be a
file in the current directory" is wrong as well).  Filename generation is
not applied to the strings inside the [[ ... ]].  Try running this:

	function fx() {
	    mkdir /tmp/x
	    echo "echo hello" > /tmp/x/x
	    chmod +x /tmp/x/x
	    echo /tmp/x/*(x)
	    [[ -n /tmp/x/*(x) ]] && echo Got nonzero string
	    [[ -f /tmp/x/*(x) ]] && echo Globbed a file
	    [[ -x /tmp/x/*(x) ]] && echo Globbed executable file
	    [[ -x /tmp/x/x ]] && echo Found executable file
	    rm -r /tmp/x
	    [[ -n /tmp/x/*(x) ]] && echo Still got nonzero string
	    [[ -x /tmp/x/x ]] || echo Found no executable file
	}
