There was a problem hiding this comment.
if this method didn't exist, add!!(abstract_array, thunk) would just dispatch to the fallback. Now that it does exist, it dispatches to the method below, which saves one accumulation. It's late and my brain hurts and I had to write this down to convince myself that it makes sense.

Its not as good as
add!!(::AbstractArray, ::InplacableThunk)but if it can be inplace then it still saves 1 allocation (InplaceableThunk woulds save 2)/
