Changelog:
============
sql
------
- Fixed critical regression in SQL expression formulation in the 2.0 series due

elements against the same operator repeatedly; parenthesis grouping would be
lost with expression elements beyond the first two elements.
typing
-------
Remove typing.Self workaround, now using PEP 673 for most methods that return
Self.
