> Yes. I thought they are the same, but interestingly, upon more research it appears that [forwarding and delegation are different in their semantics](https://stackoverflow.com/a/28539643/1576462). I believe that composition is used in many places in Julia but it may be that most people just write the delegation code manually. It would be nice to have a standard macro somewhere that is versatile enough to cover many use cases.

> I’m not quite sure I’m understanding you correctly, but it sounds like you want to define a new function for arrays, and then also extend that to a new type. It might help if you could give a broader explanation of what you’re trying to do. It’s still sounding a bit like you just want some new AbstractArray methods, in which case what you should do is define Daggered \<: AbstractArray and then simply define some methods which take an AbstractArray argument, i.e. trait(A::AbstractArray, args...…
