pathsWithCaptures

pathsWithCaptures(haystack: Envelope): [Path[], Map<string, Path[]>]
Return all matching paths along with any named captures.

isComplex

isComplex(): boolean
Returns true if the Display of the matcher is complex, i.e. contains nested patterns or other complex structures that require its text rendering to be surrounded by grouping parentheses.
