It looks stolen from functional languages, IIRC --- most languages of the Haskell or ML stable support this kind of pattern matching. It is, indeed, great.

(Although the use of special characters doesn't really fit the Lua style, which normally goes for keywords. Perhaps:

match k
  with 10, 11 then return 1 end
  with 12 then return 2 end
  with i if 13<=i and i<=16 then return 4 end

(That also ends up having a nice simple grammar, too.)
