2 Parsers with Choice🔗ℹ

Most grammars are not completely static—usually, there is an element of choice. For example, when parsing a boolean, a valid value is true or false. Even more complicated, when parsing a list of elements, a valid input might be any number of booleans, all next to one another. To handle these kinds of grammars, a parser can be provided with multiple paths, each of which are valid.
