To accommodate this change, we must allow for this object to evaluate to False for functions like _end_section which behave differently based on whether or not a Section has been started. Signed-off-by: John Snow --- Probably a better fix is to restructure the code to prevent _end_section() from being called twice in a row, but that seemed like more effort, but if you have suggestions for a tactical fix, I'm open to it.
