The name views​::​all denotes a range adaptor object ([range.adaptor.object]).

Given a subexpression E, the expressionviews​::​all(E) is expression-equivalent to:

• (2.1)
  decay-copy(E) if the decayed type of Emodels view.
• (2.2)
  Otherwise, ref_view{E} if that expression is well-formed.
• (2.3)
  Otherwise, owning_view{E}.
