I love SQL::Abstract, in particular for INSERT, UPDATE and DELETE, but it's support for SELECT is IMO a bit limited. I see its disadvantages in (t least) these areas:

1. SELECT is designed only for use for single tables, no support for any kind of JOIN
2. No support for aggregated queries, using GROUP BY and HAVING.

I'd love to see a module that supports these, but I wouldn't like to see Yet Another Incompatible Syntax. So yes, I vote for at least compatibility with SQL::Abstract, better yet, cooperation with it. That you might achieve by making your module an extension to it.

But perhaps I'd like it best if you contacted the author/maintainer of SQL::Abstract, and together find a way to merge your respective modules, making your module actually part of SQL::Abstract. Co-authorship, so to speak.
