Re: [sv-ec] Queries related to array manipulation method

Moumita,

We have been in the process of updating section 5.15.2 with mantis item 978.
Mantis 978 has not yet been approved by the committee. I have commented on
each of your examples given my current understanding of where we will end
up after we complete mantis item 978. This is my current best guess of
where we will end up.

[Neil] This testcase is valid.
       Only the leftmost "dimension" will be reversed.

[Neil] This testcase is invalid since i[1] refers to a single element and
not to an array of elements.

[Neil] This testcase is invalid since i[1][1] refers to a single element and
not to an array of elements.
