When do you use slices outside of a subscript?
More importantly, when do you need slices outside of a subscript where
they would benefit from being written in compact slice syntax rather
than function call syntax?
I think I've done something like this once or twice:
chunk = slice(a, b, step)
for seq in sequences:
do_something_with(seq[chunk])
but I don't even remember why :-)
I'm not convinced that the first line would be better written as:
chunk = a:b:step
But this definitely wouldn't be:
chunk = ::
So apart from "but it looks cool" why do you want this?
(I agree that slices look cool inside subscripts, I'm just not so sure
about outside of them.)
