GNU compatibility is preferable to CL compatibility. Please do submit
the feature request (also for documenting puthash's return value),
maybe we can have the best of both worlds.
Thien-Thi Nguyen, in http://mid.gmane.org/87y7ae6x44.fsf＠ambire.localdomain
(which has yet to show up) tells me that he’s just changed #'clrhash to
return the table. Ah, there we are:
http://cvs.savannah.gnu.org/viewvc/emacs/src/fns.c?root=emacs&r1=1.43...
I didn’t mention documenting puthash’s return value.

Good enough for me. Ship it. Oh, sorry, that's my job. One more
time -- at least. ;-)
Thanks for checking!
