The high-level intermediate representation for a word-boundary assertion.
A matching word boundary assertion is always zero-length.
Match a Unicode-aware word boundary. That is, this matches a position
where the left adjacent character and right adjacent character
correspond to a word and non-word or a non-word and word character.
Match a Unicode-aware negation of a word boundary.
Match an ASCII-only word boundary. That is, this matches a position
where the left adjacent character and right adjacent character
correspond to a word and non-word or a non-word and word character.
Match an ASCII-only negation of a word boundary.
Returns true if and only if this word boundary assertion is negated.
