Context: #462

TODO:

  • Use -O2 instead of -O1?! Or possibly specific flags?! (The differenceWith bench are significantly slower with -O1 instead of -O2, but -fspec-constr seems to recuperate most of loss.)
  • Help u-c reduce allocations by re-using the old value instead of inserting an equal one.
  • Avoid String keys?!
  • Specialization
