AOB :Equality comparison for collections
  * Jonas talked about how he wants to make the equality comparison operator
    follow more C++ semantics and raise type errors if a comparison is not
    allowed in C++
  * Yasser was very enthusiastic about this subject, encouraging to follow this
    path and also think about how it should work when comparing collections
