[Python-ideas] slice[] to get more complex slices

[Grégory Lielens]

That would be even more direct....but it require syntax support, usefull 
mainly for people doing multdim complex slicing (i.e numpy users). I may be 
wrong, but I do not see it gain much support outside numpy...

slice[....] is probably much more easy to swallow for standard python 
users, and almost as good imho.
It reuse getitem, so it imply the produced slice will behaves exactly like 
it would if it was not stored/reused, and almost garantee it will be the 
case indeed (even if the slice syntax is extended)

Getting this to work including a new module would be nice. Eventually, 
having it standard is positive too, it means slice manipulation will become 
more standardised.
