Alex,

Separate chains (IMO) is the best way to deal with collisions. If this is built in, the does not have to deal with collisions (or even know what they are)...it provides scalability without the user having to do anything.

Fixes the problem, as opposed to what? What about the htable implementation does not satisfy you now?

There are only a few ways of dealing with collisions: put them in a flat list attached to the bucket, devise some algorithm for moving the data to neighbouring buckets, etc. The list approach is by far the most common and straightforward. The best way to minimise collisions entirely is to use a good hash algorithm appropriate to the types of keys being hashed.

Alex,

It is a collision resolution, yes collisions will still happen but it essentially fixes the problem.

Why isn't htable designed to use separate chains to avoid collisions
altogether?

Chains do not avoid collisions; they're attached to buckets, and simply represent a particular data structure for handling allocations into the same bucket.
