I'm not sure what exactly you're trying to do, but maybe this will help:

void seq_apply(Func, Args...)(Func func, Args args) {
        import std.traits;
        alias ParameterTypeTuple!Func Params;
        enum ArgNum = Params.length-1;
        func(args[0], args[1 .. ArgNum + 1]);
        static if (args.length > ArgNum + 1) {
                seq_apply(func, args[ArgNum + 1 .. args.length]);
        }
}
