I am a fan of the proposal. Imagine you are programming for a memory-constrained system. By telling the list how big it needs to be you can save precious RAM.
Is it an actual use case or are you just imagining it? :) I'm asking because, unless you are only allocating that list and all the objects contained it in it already exist, limiting the list's size won't do much for the process' memory occupation.
It might help if it was a list of integers between -1 and 99 and 1-character strings.
That's not what you should use lists for if memory consumption matters. Use http://docs.python.org/dev/library/array.html, especially if your integers are in such a limited range.
Yep, and regarding the second part, a string is a very efficient way to store many 1-character strings.
