0.1.2.1

• No-op improvements
  • Minor documentation edits.

0.1.2.0

• New features

  • Officially support statement parameters

    They where technically working prior to this version, but now that I realize they can't be made monomorphic I have decided to support them officially in their polymorphic form. See the Haddocks for more information.

    I am electing to escalate this to a minor version bump when I think it could technically be a patch version (from the standpoint of "whether it compiles") to reflect the "officially supported" nature of the feature.

• No-Op improvements

  • Expand and improve the documentation
  • Some internal refactors
