If I type "hash" in the Help Desk, I get

  hash  provided from racket/base, racket

but not from ASL, in contrast to, say, "list", which gives

  list  provided from racket/base, racket
  list  provided from r5rs
  list  provided from rnrs/base-6
  list  provided from lang/htdp-advanced

and much more.

So that's the sense in which it (and other hash functions) are missing
from the docs.  [Were, I haven't tried your latest push.]

Yeah, but that just misses too many use cases.  Since the language is
already mutative, I see nothing gained.

Thanks for the new push.
