Which you would then use like:

Yep. There's a problem, though, when you bring in subtransactions. The
logic wants to be like this:
Is there some reason you can't simply do this?
with new_transaction(conn) as tran1:
tran1.query("blah")
with tran1.subtransaction() as tran2:
tran2.query("blah")
with tran2.subtransaction() as tran3:
tran3.query("blah")
# roll this subtransaction back
tran2.query("blah")
tran2.commit()
tran1.query("blah")
tran1.commit()
