fancy slicing does not seem to work with extended indexing operator

[nilsbecker]

open Owl.Dense.Ndarray.D
let a = uniform [|3;3|];;
get_fancy [I 2; R[0;1]] a;;
a.!{I 2; R [0;1]};;

the last line gives

Error: Unbound value .!{}
Hint: Did you mean .${} or .%{}?

on ocaml 4.12. i was unable to dig up the place where the indexing operators are defined as merlin was of no particular help.

They are defined in the owl_operator.ml file, have a look at this PR: #543

In particular, I think you would need to add it to the Make_Ndarray functor

[nilsbecker]

ah ok. the book seemed to imply that this was already included.

[mseri]

I think it would be convenient to have them. I cannot speak for everybody but I would be favourable to a PR introducing them, especially since there is a discrepancy with the documentation

The example code seems to work ok in the current version of Owl.
