Dunno why they're called research _councils_. They've never arranged collection of my research bins or sorted out the potholes in my notes.

I think this is what ViewPatterns are for, though maybe they don't work well with GADT like structures?

"Absolute value" bars? |C| is the discrete version of C. I feel like this is quite common.

"Generative effect" is already used in PL theory to mean things like name or reference cell generation. See things like generative vs applicative functors in ML modules.

Pullback? Because the functors involved are all going to be forgetful. Cartesian categories probably won't be the apex tho: I don't think that the surjectivity law will be required (<pi_1,pi_2> = id).

Did you know that trains in the UK run on Lenses? I've been working for @Tracsis for the last five weeks and we're hiring Haskell developers! Please spread the word :)

The second paragraph of Section 2 indicates that it is an abbreviation for 'o → (o → (o → o))'. I don't know why this abbreviation isn't used consistently.

There are no stack backtraces, only lists of promises your program failed to keep. twitter.com/tpolecat/statu…
