values_at

        # MatchData.values_at

(from ruby core)
---
    mtch.values_at(index, ...)   -> array

---

Uses each *index* to access the matching values, returning an array of
the corresponding matches.

    m = /(.)(.)(\d+)(\d)/.match("THX1138: The Movie")
    m.to_a               #=> ["HX1138", "H", "X", "113", "8"]
    m.values_at(0, 2, -2)   #=> ["HX1138", "X", "113"]
    m.values_at(1..2, -1)   #=> ["H", "X", "8"]

    m = /(?<a>\d+) *(?<op>[+\-*\/]) *(?<b>\d+)/.match("1 + 2")
    m.to_a               #=> ["1 + 2", "1", "+", "2"]
    m.values_at(:a, :b, :op) #=> ["1", "2", "+"]
