Just a small comment that I also think the :greedy approach is very similar. I think the length 0 argument to the `Channel` is the implicit default value, so I...

Unfortunately I also don't have the bandwidth for this now. I would need to look into this approach more (as I am not familiar with it), but I am not...

The reason I changed it back is because I cannot have the ```julia @testset ... for b in backendlist include("some_file_which_wants_to_use_b.jl") end ``` pattern.

Would it be useful to have that `@include` definition in TestExtras.jl? In order not to have to copy paste it everywhere?

Unrelated to this issue, @XingyuZhang2018 has also been looking at performance of KrylovKit with CUDA / GPU data and found it to be not meeting expectations. It is thus probably...

A first attempted explanation for possible suboptimal performance, was the observation that `dot` has terrible performance on nested arrays, as indicated by the following timings: ```julia-repl julia> @testset "dot $atype"...

Actually, it would still be interesting to see where the allocations are coming from in those cases, but they do not seem to affect timings significantly. I found this presentation...

That is a great test case to focus our attention on! Is the fact that you have several vectors wrapped in a list essential to this, or is it already...

Dear @Yonatan-Nissan , I think your request for a memory-bounded contraction is a valid one. However, I currently don't have the bandwidth to implement this, and in fact also lack...
