SourceScope class
A special intermediate scope used for nodes that don't see columns and tables added to the statement they're in.
An example for this are subqueries appearing in a FROM clause, which can't
see outer columns and tables of the select statement.
Another example is the InsertStatement.source of an InsertStatement,
which cannot refer to columns of the table being inserted to of course.
Things like INSERT INTO tbl (col) VALUES (tbl.col) are not allowed.
