|---|---|
| 🔗m.size() | 1 + e.mark_count() |
| 🔗m.empty() | false |
| 🔗m.prefix().first | first |
| 🔗m.prefix().second | first |

| 🔗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. |
