Can't we write self.indices.borrow()?

Weird, that work, when I originally tried doing that I got an error, but now it works.

Non-markdown expert here: Is the (crate::Itertools::array_combinations_with_replacement) required?

I don't know I just copied and modified the doc comment from two lines above.
The whole combinations_with_replacement file seems to feature gated under Edit: |

I added test for |

Thank you. Could you fix so that CI runs through?
Can you limit the cfgs to where they are necessary please?
And by the way: Thanks for splitting up the PR into nicely diffable chunks, and for just amending instead of force-pushing and overwriting old commits.

We can think about returning Box<[T]> later, but since we'd probably construct it via a Vec, Vec is fine.

I just what did not change that, as that was the way it was before.

Maybe we should remove the |
`combinations_with_replacements` as they are done at a module level right now.

This PR adds a new method for iterators called
array_combinations_with_replacementwhich is similar tocombinations_with_replacement, except for that it uses const generics and arrays.This is similar to
array_combinationsandcombinations.I also generalized the underlying
CombinationsWithReplacementtype similar to how it is done withCombinations.This closes #1025.
