Up-to-date Opaleye

Tom Ellisrequested to merge
tomjaguarpaw/haskell-orm-comparison:master into master

Hello William,

This MR brings your ORM comparison up-to-date with latest Opaleye and solves three problems that you mentioned on your blog post:

  • Left joins are now inferrable
  • There are type safe aggregators for summing
  • It uses Monads instead of Arrows

It requires the following versions. I don't use stack so I didn't know how to update that.

  • opaleye >= 0.6.7006.1
  • product-profunctors >= 0.11.0.0

I would be grateful if you could also update your blog post to reflect this, or if you have a public repository with the blog content then please point me to it and I can edit the post.

Cheers,

Tom
