Hash table functions not all there

[David A. Moon <Moon at SCRC-TENEX at MIT-MC>]

I agree with you.  Could you (or someone else) send in a concrete proposal
for what is missing?

For reference, here is a list of the interesting messages to hash tables
in the Lisp machine.  I have censored internal messages and messages
that all objects handle.  Clearly not all the operations you request are
here, although ones for finding out the size (both allocated and in-use)
are.

(:CHOOSE-NEW-SIZE :CLEAR-HASH :COPY-HASH :FILLED-ELEMENTS :GET-HASH :GROW :MAP-HASH
 :NEW-ARRAY :NEXT-ELEMENT :PUT-HASH :REM-HASH :SIZE :SWAP-HASH)
