To Do

Features

Add a way of choosing a table's initial capacity and max occupancy rate, either by giving more parameters to the functor Make_, or by giving more parameters (with default values) to the function create. Check whether this degrades performance (with and without flambda).
Add missing operations: filter_map_inplace, fold, to_seq, add_seq, replace_seq, of_seq, to_seq_keys, to_seq_values.
Check (improve) compatibility with Stdlib.Hashtbl, either by ensuring that our API matches the Stdlib API, or by providing a submodule that emulates the Stdlib API.
- create : take capacity as an argument
- add and replace : return nothing
- need find_opt
- need length as a synonym for cardinal
Develop a Sentinel module. Make extends an existing type with one fresh sentinel. MakeMany extends a type with n fresh sentinels.
Think about a concurrent variant of this data structure. Shrinking or growing the table requires blocking insertions and deletions (but not lookups). An insertion or deletion operation can be committed by a CAS on the key array. The table's population and occupation fields can be updated (via fetch-and-add) after the commit point, but this seems to imply that the current value of these fields can never be trusted unless the lock has been taken.
