Building a language is fucking hard, man.

Very nice way of transitioning from Lisp to Haskell. The Lisp library is also very cool.

Some nice patterns, both in the main body and the comments, for implementing lenses with a light sprinkling of category theory.

What I enjoy most about these (semantic) editor combinators is that their use is type-directed and so doesn’t require much imagination. When I have the type of a complex value, and I want to edit some piece buried inside, I just read off the path in the containing type, on the way to the buried value.
