Introducing Emblem - TypeKeyMaps

This is the third post in the Introducing Emblem series, where I discuss a reflection-based utility library I have developed called emblem. If you want to try emblem out on your project, follow these instructions. Or read this if you just want to explore try it out in the Scala REPL.

In the previous post, we looked at the core building block of the emblem library: the TypeKey. In this post, we begin to explore the utility of the TypeKey using TypeKeyMaps.

Monads in Scala Part Three: Lisst[A]

We continue our Monads in Scala series by reviewing and translating the third page of the chapter on monads from the Haskell wikibook. This page takes quite an interesting view on lists, as it does not treat lists as things that you cons onto or even look things up in. It manages to treat lists nearly entirely as monadic structures. It even manages to come up with a couple of examples of using lists that only use the basic monadic operations. To view lists as things that we cons onto, we have to wait for a later page on additive monads.
