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?

Is `a[ _, 9, R(2, $, -3)]`

equals to

`a[0..$, 9, 2..$].reversed!2.strided!2(3)`
or
`a[0..$, 9, 2..$].strided!2(3).reversed!2`
?

My bad. You have already wrote `iota(a,b,-s).reverse`.

We can test this kind of syntax in Mir first https://github.com/DlangScience/mir
