When an <<ref_array>> is formatted to a {std_ostream}, the result is a valid JSON. That is, the array will be output with square brackets and the comma separated list of values, as per the JSON specification.

We can query a value for its underlying representation of a particular kind in a way that does not throw exceptions by requesting a pointer which may be null, instead of a reference. Here we use <<ref_value_if_string,`value::if_string`>> to conditionally perform an assignment without using exceptions:

However, as shown above these functions throw an exception if the kind in the <<ref_value>> does not match the kind denoted by the function signature. This can be used as a concise form of validation: access values as if they were the right type, but handle the resulting exception indicating if the schema of the JSON is not valid.
