I started an investigation ("blame" in the web pages of our code is even more powerful than I thought (for each line, we can have navigate its history)): In #31 it was added and was actually fused. Then the commit that is interesting us here is https://github.com/rust-itertools/itertools/commit/beaf3955b51f5a5a2c5861d34ebd591736377b84 (by bluss, he missed one comment in this "unfuse" commit that you found).

I'm fine with either unfused or fused, but I'd vote for uniform behavior. Not sure if we have a general guideline regarding fusedness, though.

I agree.
I think it would be great to have a clear guideline about fusedness. And maybe better tests about (un)fusedness. I'm not sure all the iterators behave correctly in that regard (and have correct documentation).
It's not very high on my TODO list though as I'd rather triage/complete old issues/PRs and work on fold
specializations and maybe_/Try
to eventually move to use const-generics.
I'm gonna make an issue about fusedness to see opened issues and PRs related to it, clarify the situation (like make a guideline) and eventually make a TODO list about all this.
In my book,
InterleaveShortest
should not produce more items thanInterleave
, but so far it did for unfused source iterators.This PR brings
InterleaveShortest
in line with Interleave. The documentation already (incorrectly) stated thatInterleaveShortest
is fused.Related to #533.
