🔗	Element	Value
🔗	m.size()	1 + e.mark_count()
🔗	m.empty()	false
🔗	m.prefix().first	first
🔗	m.prefix().second	first
🔗	m.prefix().matched	false
🔗	m.suffix().first	last
🔗	m.suffix().second	last
🔗	m.suffix().matched	false
🔗	m[0].first	first
🔗	m[0].second	last
🔗	m[0].matched	true
🔗	m[n].first	For all integers 0 < n < m.size(), the start of the sequence that matched sub-expression n. Alternatively, if sub-expression n did not participate in the match, then last.
🔗	m[n].second	For all integers 0 < n < m.size(), the end of the sequence that matched sub-expression n. Alternatively, if sub-expression n did not participate in the match, then last.
🔗	m[n].matched	For all integers 0 < n < m.size(), true if sub-expression n participated in the match, false otherwise.
