@mike: thanks ! It looks like SA’s developers are also more helpful than their Hibernate counterparts And subtransactions have been around (and documented) at least since 0.4.x, so I have no excuse for not taking advantage of them So, I will look into it and see how much of my code can disappear thanks to this feature. (however, I guess the cleanup code will still have to be called when the session is no more active, right ?)

  _session().close()
  session_maker.remove()

@mathieu: I was talking about the perfect’ish Ruby, but Brainfuck would have been a candidate as well if it were more popular

“you simply don’t like languages that use half of the keyboard’s non-letter keys as metacharacters”

Are you talking about Brainfuck?

Seriously, it gives me a good overview of the tools I might need for rainy days when I want to try something different than ruby.

Thank you for this thoughtful overview. You’re way beyond my experience and capabilities, but your even-tempered writing style inspires confidence. Already, I want to check out some of your picks, nose in particular.

took a look at your _transactional.py module. I think the SQLA session does a little more than you think. It does in fact do the “increment/decrement” thing with nested begin/commit pairs, where the “outermost” commit wins. Just use begin(subtransactions=True). I did use Hibernate / Spring and even EJB for quite some time so SQLAs design is well aware of those concepts.
