Subject: Is there utility in making hash-table-{keys, values} built-in functions?

Hello all,

I noticed that the functions hash-table-keys and hash-table-values are just
wrappers around maphash. This means that there is no way to iterate over a
hash-table without using a lambda.

Would it be useful or worthwhile to implement these directly in C? I don't
know much about low-level Emacs development, but having these as built-ins
could make iteration of a hash-table a little faster and easier to debug.

Shankar
