Ladies and Gentlemen:
I present to you Michael Bayer, the amazing multitalented developer
of SQLAlchemy--getting more done in one week than the average team of
developers does in a month!! Not only is he a very fast coder, but he
writes comprehensive documentation for his code--an
()
statement, which will make it use cursors in the default manner.

After updating to HEAD this morning I got an error. This code has
worked with many versions of SA and I've never seen anything like
this error before. Here's the relevant code (modified from its
original version to fit your screen):

Hi Mike,
I've been lurking here in the shadows for a while...this particular topic looks
very interesting to me and I'd love to upgrade to HEAD to try it out. However,
I'm wondering what the risk factor is in doing that? Have there been any other
major (potentially destabilizing) changes
I just looked at SA's PickleType and came up with a couple of issues.
1. dumps/loads
It looks like you can provide a custom pickler to PickleType, but the Python
Pickler class does not have dumps()/loads() methods. Those methods are only
available at the module level. This is a minor issue

Oh yeah, I forgot to mention that many of my class constructors take a parent
object as one of their arguments, which explains the slow instantiation.

BTW, this post started out as a reply to James but grew into a collective
