I also want to use the opportunity to clarify that this Arel impl is current 
with the latest version and contains all of the current features. At least as 
defined in the rails Arel impl. All additonal features around it are more 
related to ActiveRecord features constructed around it (that I might also 
implement as different modules in the future). I've also seen other Arel forks 
with different features but this is not the main Arel.

I can't run the code, the dist has many undeclared/unpublished
dependencies. I would likely have more useful things to say about it if
I could run it.

Yes, but in a limited fashion: for people who require familiarity with
the Arel API or want to port code that uses Arel.

If I were to design an AST that aims to please everyone, I would give
it a plumbing and porcelain layer, both user accessible, and the
plumbing layer would map very closely to the parse tree, and the
porcelain would be a set of the features available in Arel, jooq,
sqlalchemy, linq etc.

I agree that they are ripe for displacement. I have looked into this
topic before and found that DBIC is coupled quite tightly to
SQL::Abstract. If you want instant adoption from a large userbase, aim
to work so that DBIC can choose between SQL generators.

You have not picked a proper name yet. I think SQL::Arel is fine,
that's what the Pod name section already hints at.
