insert (value) at (index) on lists? #166

Closed KimBruce closed 5 years ago

KimBruce commented 6 years ago

There apparently is no insert operation in lists to squeeze in a new element, moving some elements to the right to make room for the new one. It seems odd to me that we have a remove(n) method, but no insert (val) at (m). Obviously not a huge deal, it just seems a bit asymmetric. (Of course we do have at(m) put (val).)

I'ld be happy to have someone implement this. There need to be tests, or course, especially for the boundary cases of m being one beyond the end of the list, and being at the end of the list.

Still needs to be written -- I'll take care of it.

This method was added in minigrace commit 4d33d8a
