> 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.
