There was a problem hiding this comment.
Just a minor note from the sidelines: there is a discussion in this PR why this method is needed, and why removing it would be possible, but would require changing code/behavior for which in turn it is unclear why it is the way it is.
After this PR, there'll be one more layer which when reviewed in a couple years, people will wonder "why is it this way?" and a future PR might also say "it is unclear why it is there" just referencing this method now?
Of course they can dig through old commits, then look up the corresponding PRs, read the discussions there, rinse and repeat ("code archaeology").
Live would be much easier for those poor future developers if there was a brief comment here summarizing this (and if there had been such a comment in the code you were wondering about, I am sure that would have been helpful, too... :-/).
Anyway, just my two cents as a bystander. You do you :-). For what it's worth, I'll appreciate your contribution either way :-)

Yes, a comment here would make sense if we decide to retain this method
There was a problem hiding this comment.
Looking at the git blame, it seems support for non-conforming UnitRanges was added intentionally in #27302, and is pre-1.0 behavior(!). In light of this, I'll add a comment now to link to that discussion, but in the future, it might be better to return StepRanges automatically in such cases by checking the type of something like oneadditiveunit, as discussed on discourse.

If there are no further comments, would this be good to merge? |

Currently, `Array(r::AbstractRange)` falls back to `vcat(r)`, but certain ranges may choose to specialize `vcat(r::AbstractRange)` to not return an `Array`. This PR ensures that `Array(r)` always returns an `Array`. At present, there's some code overlap with `vcat` (just above the `Array` method added in this PR). Perhaps some of these may be replaced by `unsafe_copyto!`, but the tests for ranges include some special cases that don't support `getindex`, which complicates things a bit. I've not done this for now. In any case, the common bit of code is pretty simple, so perhaps the duplication is harmless. (cherry picked from commit 3cc0590)
