The minimum working case would be: Let say I have a vector of mixed types: x = [ isodd(i) ? rand(Int64) : rand(Float64) for i in 1:1000 ] I want to sum these numbers, with: function mysum(x) s = 0. for val in x s += val end s end This turns out to the be slow because of the type in…

It is even more simple then that. If all types are subtypes of some abstract class, then you can use subtypes function to generate list of all subtypes. It’s little more involved in case of parametric case, so I am not sure whether it is possible to write generic macro that can solve them all, but i…

Great that that had been done. I will see if I understand that implementation.
