Hi there,

I am wondering whether JSON [RFC7159] support would be a helpful extension to the C++ standard library (pure library extension), including, but not limited to, the following aspects:

1. A variant-like container type (for this mail, let's call it "std::json") that combines C++ types for the JSON value types [RFC7159, chapter 3]:
  - string (e.g. std::string),
  - number (e.g., double or int64_t),
  - boolean (e.g., bool),
  - array (e.g., std::vector), and
  - object (e.g., std::map).
