I'd forgotten that I filed that bug. ;-)

 At the very least the byte-compiler should warn about it, indeed.

A warning is _no_ substitute for raising an error.  Adding a
warning for byte compilation is worse than doing nothing, IMO.

The doc clearly says that an even number of args are _required_.
