It's tricky code :-) But it's a nice exercise for C++11 template 
programming.

Most of your code is very similar to mine, but I can also see 
many little differences, so it seems you have written your 
translation from scratch.

In your code you have left the original C++11 naming conventions:
struct step(Direction d, Left, Right) {

But in D it's better to write:
struct Step(Direction d, left, right) {

In type_list_to_vector you have solved the problems in a simple 
way and using a quite different way.

Thank you,
