> BytesBytes has table stores keys in the byte array for compact
> representation, however that means that the straightforward implementation of
> lookups serializes lookup keys to byte arrays, which is relatively expensive.
> We can either shortcut hashcode and compare for common types on read path
> (integral types which would cover most of the real-world keys), or specialize
> hashtable and from BytesBytes... create LongBytes, StringBytes, or whatever.
> First one seems simpler now.
