When I use the term I refer to the ability to build higher level
abstractions. Here's a perfect example:


This library implements RFC-7519 and uses objects of type
nlohmann::json in its public interface.

I argue that boost::json::value would be a superior type to what this
library currently uses. That is what is meant when Boost.JSON claims
to be a "vocabulary type." It certainly does not mean that arbitrary
precision numbers are supported, that every possible use-case is
supported, or that it can store any payload with perfect fidelity.
