Problem

When parsing a statement, if it contained a section expression, and that section expression successfully parsed and claimed a section (but the statement itself failed in init), the claim on the section would not be released. As a result, any future attempts to parse a section expression would fail as it believed the section to already be claimed.

Solution

When a section expression may be parsed, the Statement iterator is wrapped such that the "owner" of the section context is cleared when the next element of the iterator is returned.

Testing Completed

tested in game using a combination of addons that exposed the issue. testing is a bit complex as it would require usage of priorities which isn't currently possible with test syntax. if it is really wanted i can probably make it happen
