  2. Benchmark HashPSQ

    - lookup performacne 3x slower than HashMap, 10% slower than Map
    - minView 3x faster than GHC_PSQ
    - lookup 1.15x faster than GHC_PSQ
    - insert of non-existent keys 3x faster than GHC_PSQ
    - insert of existent keys 1.17x faster than GHC_PSQ

  1. Compare performance to specialized GHC.Events.PSQ

    The new 'IntPSQ' is 25% faster on lookups and about 3x faster on inserts.
    Sweet :-)

  1. Implement draft of a more compact IntMap

    The trick is to store keys in inner nodes and use them instead of the prefix
    to store the prefix that is shared by all keys at this node and the nodes
    below. Getting rid of the prefix and one level of leaf-nodes reduces the
    storage overhead from about 6 words per node to only about 2.5 words per node.
    The inner nodes are selected such that they have the smallest key of all the
    nodes sharing the prefix. This is necessary to still get an efficient
    `toAscList` and it has the nice benefit that findMin becomes O(1).
    I have not done any benchmarking yet, but I expect this structure as fast as
    the existing IntMap's, as we're doing less allocation, but a bit more
    operations per node.

  1. Fix and reinstate the recently commented tests.

    The not working tests were using the join function which we renamed to
    link because of Applicative being introduced to Prelude. Nevertheless,
    I forgot to update the tests. Fixing now.
