[Lua] Capturing all captures

Quick q. How did I get table w/ all captures from string.match() ?

Currently I use something like this:
    c1, c2, c3 = string.match(s, pattern)
    captures = { ["\\1"] = c1, ["\\2"] = c2, ["\\3"] = c3 }
Obviously, this is not how it should be.

why don't you use a generic for looping through the results of string.gmatch?
