It will be more obvious when you pack a few `instruct` together, e.g using chained put blocks. ```julia using StaticArrays, BenchmarkTools U = @SMatrix rand(ComplexF64, 2, 2) st = rand(ComplexF64,...

But `SMatrix` should be faster ```julia julia> @benchmark foreach(k->instruct3!($st, $U, 2), 1:100) BenchmarkTools.Trial: memory estimate: 80 bytes allocs estimate: 1 -------------- minimum time: 10.900 ns (0.00% GC) median time: 13.812...

I got errors when using the function factor unless I import it explicitly. It is annoying to write this extra line just because of something rarely be used.

From what I see here, you only need to remove the export, and that's all. Is there any external package depends on this? And what I mean is not export...

OK, that sounds reasonable, I would like to keep this function then. But I still feel strange for importing this manually especially this will be in our example. I mean,...

The definition of composition is Block constructed by other blocks. The reason why RotationGate is primitive is because the usually we only use XYZ block and use that as a...

The only two primitive blocks that remains questionable are `RotationGate` and `TimeEvolution`, but the reason why they are primitive is also simple: - the block inside `RotationGate` is just a...

`Daggered` will be part of the symbolic computation (which are all special marks on block and are composite blocks), or it would be hard to optimize things like the following:...
