I am curious as to how Julia’s compiler handles if statements in type parameters. Does it select one specific branch based on the arguments which will always be true as the type parameter is constant, or does it keep checking the if statement in every loop iteration? And if the latter is true, woul…

I think this is the question: julia> f(a) = isa(a,AbstractArray) ? 1 : 3.0 f (generic function with 1 method) …

Cost of checking if statements in type parameters in a big loop and generated functions

Fair enough, thanks a lot.
