There was a problem hiding this comment.
Maybe we can also say without parTupled, then an effect would execute from left to right.
Maybe also it could be worthwhile to mention mapN and parMapN at the same time since they are quite similar.

In my experiences working with Cats users, awareness of
tupledandparTupledis not high, considering how fundamental and useful these operations are. Attempt to raise the exposure plus a bit of relevant cross-linking in the docs.Thank you for contributing to Cats!
