Densely packed tweet there… sorry if it’s confusing at all. I’ll happily discuss long form on GitHub. Twitter doesn’t really support these kinds of conversations.

There are lots of monoid instances… some ship with Cats and many don’t. We elected to give a taste for the pattern but not go into too much detail. You can experiment on the REPL and SuperAdder provides more context. We’re happy to take suggestions via Github though!

Ah. Good point! You don’t need one at all, my bad. Thanks for the spot. If you raise an issue against the book I’ll fix the text when I’m back in the office.

This could be improved, certainly. The exercise is saying that your definition of setMonoid should be generic across the type parameter to Set. If you have setMonoid and intMonoid in scope you can get a Monoid[Set[Int]]. Hope that makes sense!

Haskell evangelism tip: if you don't like a language then don't tweet about it. There's no such thing as bad publicity and negative comments turn people off the Haskell community. Instead, tweet about something positive built in Haskell

I hadn't heard of JSON LD before. I'll definitely check it out. Thanks for the link!

Definitely! Standardised schema formats are very useful. But I think these problems exist in dynamically typed languages as well. The expression language stuff I'm talking about at the end would be the same in Python as it is in Scala.
