pep-484: the pep-484ening, SQL part three
hitting DML which is causing us to open up the
ColumnCollection structure a bit, as we do put anonymous
column expressions with None here. However, we still want
Table /TableClause to have named column collections that
don't return None, so parametrize the "key" in this
collection also.
* rename some "immutable" elements to "readonly". we change
the contents of immutablecolumncollection underneath, so it's
not "immutable"
