Just starting to look at boost MPL, say I have 2 vectors that I want to combine, is it possible with the boost MPL or do I need to write the code myself?

Say I have:

typedef vector<Class0, Class1, Class2, Class3> vec1;
typedef vector<Class4, Class5, Class6, Class7> vec2;

I did try push_back but I do not get the expected result:

typedef push_back<vec1, vec2>::type combinedVec;

What I end up with doing the above is a vector as follow:

vector<Class0, Class1, Class2, Class3, vector<Class4, Class5, Class6, Class7>>

What I want instead is:

vector<Class0, Class1, Class2, Class3, Class4, Class5, Class6, Class7>

Any help will be appreciated

seems like that the types of the second vector aren't resolved. Looking into this, beside that I do not know whether someone would need this :D – realvictorprm Jan 06 '17 at 08:34
@ArthurM. This question is actually a case of the XY problem, but with that said, even if it is, I would still personally like to know the solution to this specific issue. – CJCombrink Jan 06 '17 at 08:59
I'm currently digging into this. I want to know the solution too :) – realvictorprm Jan 06 '17 at 09:00
Can this be seen as bug or is the behaviour intended? – realvictorprm Jan 06 '17 at 09:31
