Have you considered adding support for SELECT DISTINCT ON? See here for an example.

Features on esqueleto usually are implemented as soon as someone who needs them steps up to do so. If you would like to take a stab, I'll help you with any questions that may arise :).

I ended up doing this for now. I'm pretty busy now, but maybe I'll get back to this once this project is done.

Is there something fundamentally complex about implementing DISTINCT ON in a SQL DSL? I've seen more than one DSL out there missing that specific piece of functionality. Might be very important to know before someone attempts to add it to esqueleto. I started looking into it, but it's a bit above my skillset right now, given my current experience with Haskell.

There is now support for DISTINCT ON since esqueleto-2.2.4, released a few moments ago.
