10.1.0

[10.1.0] - 2018-04-12

Added

• Vector, OrdMap and HashMap now implement Index and
  IndexMut, allowing for syntax like map[key] = value.
• Added cons, snoc, uncons and unsnoc aliases where they were missing.
• Everything now implements Sum and Extend where possible.

Changed

• Generalised OrdMap/OrdSet's internal nodes so OrdSet now only
  needs to store pointers to its values, not pairs of pointers to
  value and Unit. This has caused OrdMap/Set's type constraints to
  tighten somewhat - in particular, iteration over maps/sets whose
  keys don't implement Ord is no longer possible, but as you would
  only have been able to create empty instances of these, no sensible
  code should break because of this.
• HashMap/HashSet now also cannot be iterated over unless they
  implement Hash + Eq, with the same note as above.
• Constraints on single operations that take closures on HashMap and
  OrdMap have been relaxed from Fn to FnOnce. (Fixes #7.)

Fixed

• Hashes are now stored in HashMaps along with their associated
  values, removing the need to recompute the hash when a value is
  reordered inside the tree.
