Thanks, but I'm talking about the variadic case where the number 
of input arguments are unknown (>= 2) where the function header 
looks something like

import std.traits : allSatisfy, isStaticArray;

auto append(R, Args...)(auto ref Args args)
     if (args.length >= 2 &&
         allSatisfy!(isStaticArray, Args))
     // TODO all ElementTypes have CommonType
{
     // ...
}
