missing construct List from UList

seems to be handled by this one:

template<class T2>
explicit List(const List<T2>&);

only noticed when I tried to inherit constructors from List in a derived class.

IMO the constructor from dissimilar types is rather dangerous:

//- Copy constructor from list containing another type.
template<class T2>
explicit List(const List<T2>&);

mentioned in commit a8c40cc8

Use createList factory method instead. Eg,

  auto scalars = scalarList::createList
  (
      labels,
      [](const label& val){ return 1.5*val; }
  );
