I was needing a way to concatenate an undefined number of tuples. I came up with tuplejoin(t1::Tuple, t2::Tuple, t3...) = tuplejoin((t1..., t2...), t3...) tuplejoin(t::Tuple) = t This works julia> tuplejoin((1,2),(3,4),(5,6)) (1, 2, 3, 4, 5, 6) However, while it is fast for two or three tuples, …

[image] pablosanjose: julia> @inline tuplejoin(x, y, z…) = tuplejoin(tuplejoin(x, y), z…) This base case is backwards. It should be: julia> @inline tuplejoin(x, y, z...) = (x..., tuplejoin(y, z...)...)
