- Ilya (7/16) Jan 08 2016 Is `a[ _, 9, R(2, $, -3)]`
- Ilya Yaroshenko (5/24) Jan 08 2016 My bad. You have already wrote `iota(a,b,-s).reverse`.

i wrote my own tensor library a while ago and it allows the more convenient matlab/python+numpy like syntax: a[ _, 9, R(2, $, -3)] these are allowed: R() or _: full range for an index R(a,b): a..b R(a,b,s): when s>0, iota(a,b,s) R(a,b,s): when s<0, iota(a,b,-s).reverse Could we have this in ndslice?
