Hello
I'd like to know if you think it could be feasible to have a
Python-like syntax for indices in array and vector?
I find it so obvious and practical.
let i = ~[1, 2, 3, 4, 5]
i[1] returns a the second item ("2")
i[1:] returns ~[2, 3, 4, 5]
i[:-2] return ~[1, 2, 3, 4]
i[-2] returns ~[4, 5]
i[1,-1] returns ~[2, 3, 4]
Thanks !

This has been proposed in #4160, and was even mentioned in Niko's recent
"Treating vectors like any other container" blog post[1]; although, as
Daniel says, they would return slices (&[T]), not new allocations.
