A finger into a json value indicating where a parser is currently operating. When a parser focuses on a key-value pair in a map, it adds Key constructor to the context, and when it focuses on an element of an array, it adds an Index constructor. Like all zipper-like data structures, it is, in a sense, reversed, which makes it cheap to construct while parsing.

Convert Context to textual representation using UTF-8 as the encoding scheme. This reverses the context to present it in the expected order.

Reverse the context, converting it to a Path. For example, toPath performs this conversion:

12.bar.foo.Top ==> foo.bar.12.Nil
