In other words, PostgreSQL provides an alias for "WHERE s IN (...)" and calls it "WHERE s = ANY(...)". Forgive me for being underwhelmed.

It's not surprising that SQL is going to look at a lot like the junction operators - both operate on sets*. A relational database is nothing more than a set theory machine. The junction operators are similar. You even have all() and one() in SQL; they're just not in the forms you're thinking of.

*: Yes, the junction operators deal with lists, but they treat the lists as sets.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
