Reduced code is here.
( I wanted to reduce more but couldn't )
---------------------------------------------

// from std.typetuple
template TypeTuple(T...) {
  alias T TypeTuple;
}

template staticMap( T...) {
  static if (T.length == 0) {
    alias TypeTuple!() staticMap;
  } else {
    alias TypeTuple!( staticMap!( T[1 .. $] ) ) staticMap;
  }
}

// from std.typecons
struct Tuple(U) {
  template FieldSpec() { }

  template parseSpecs(T...) {
    static if (T.length == 0) {
      alias TypeTuple!() parseSpecs;
    } else {
      alias TypeTuple!( FieldSpec!(),
                      parseSpecs!( T[1 .. $] ) ) parseSpecs;
    }
  }

  alias staticMap!( parseSpecs!U ) Types;
}

// instantiating
void main()
{
  0; // to cause the _first_ error
  Tuple!int a;
}
