So you mean this? ```julia julia> using SplitApplyCombine julia> a = [[[1,2], [3,4]], [[5,6], [7,8]]] 2-element Vector{Vector{Vector{Int64}}}: [[1, 2], [3, 4]] [[5, 6], [7, 8]] julia> flatten.(invert(a)) 2-element Vector{Vector{Int64}}: [1,...

These are two other ways of writing it. ``` julia> map(flatten, invert(a)) 2-element Array{Array{Int64,1},1}: [1, 2, 5, 6] [3, 4, 7, 8] julia> invert(mapmany(invert, a)) 2-element Array{Array{Int64,1},1}: [1, 2, 5,...

See #341

`` I'm noting that there have been several sensible and minimal PRs sitting around, some since July, and others since quite recently, with not even a comment. These include #317...

I don't think I see any problems...
