Hi, I didn't get into details yet, I have questions:

 1. did you consider providing the same containers without asking for types?
   In most of my usage of such containers I don't know which types
   will get in in the end because the container is shared between different
   "modules" all inserting data inside.
  maybe a heterovector<> type that would take anything would be useful to
others too?

 2. did you consider other kinds of non-standard containers?
   I think in the discussion you linked I posted examples of heterogeneous
containers I use in production
   that do not have equivalents in std. From memory:
   a container of 1 value or none for each type, not more, the type(id)
being the key to access the value.
