[sv-ec] Queue Methods - return status?

Hi, All -

This question has been posed to me a number of times and I am not 
100% sure what the answer should be.

Do the queue methods return any type of status if they fail? Looking 
over the LRM (clause 7.11.2 in Ballot Draft), the methods are 
described, but unlike mailbox methods, there does not appear to be 
any return status, nor is there any description of what should happen 
if the called methods fail.

Examples:
insert() method at an index. What happens if you try to insert into a 
queue at location 5 if there are only two entries in the queue? And 
where is the behavior described. This is a void function.

delete() method at an index. Same type of issue. Deleting an entry 
that does not exist.

pop_front() or pop_back() from an empty queue. What happens? Any status?

The push_front(), push_back() and size() methods should all be okay.

Thanks for any thoughts.

Regards - Cliff
