Re: [PATCH] Add new function to test whether a key is present in a hash table.

To me the answer is usually no, unless it's speed-critical.

PS: I think a more interesting function to provide would be some
gethash-ref which would return some kind of "reference" to the entry, so
we can afterwards update that hash-table entry without (re)computing the
hash (i.e. some kind of equivalent to `intern` after which you can just
do `set` which doesn't involve hashing any more).  But that would imply
a fairly significant amount of design to make it work.
