Overview

Reading inside a JSON document, which is what Predications#dig and Predications#dig_text build. Every adapter can do it and no two spell it alike: PostgreSQL walks an array of steps, SQLite has the operators with a $ path, and MySQL has the functions -- which is what this uses for that family, since MariaDB answers to the same adapter and has no -> at all.

The path is turned into a string either way, so a key with a space or a quote in it travels as itself rather than having to be refused. What a dug value compares with is JsonComparable's to say.
