Comment on Introduction to Category Theory in Scala by Pete Kneller

Fantastic post Heiko. Very clear and well thought out. Thanks!

Like other readers I got stuck for a while on the use of symbolic type parameters, and the infix notation, but the comments have sorted me out there.

I thought I understood functors and applicatives from playing with Haskell, but couldn’t wrap my head around the more general concept of a Category. This post, with those diagrams, has gotten me that much closer to grasping it. Thanks again!

>> dummkopf (screamingly funny for a German like me, according to http://www.dict.cc this seems to be a proper English verb)

You probably meant “English noun”?

Heiko,

from my own experience, I think your book is also useful and joyful for developers who don’t find FP tough. (Not that you stated this, just wanted to point it out).

Btw, I got here by searching for applicatives after reading the example about scalaz’s validation in your book.
