I think we could support this case for init([f,g,h], data) (ie all function initialized to smae data) with just data = [data]*len(function)

for (f, d) in zip(functions, datas)

would use "init" instead of pad as the generic case

Not even one mapper per function?

Would mix dtype to test "general" case
