You could "abuse" the ability to use a function in string.gsub.

    string.gsub(line, matcher.pattern, function(...)
                matcher.func(self, line_i, ...)
            end, 1)

The 1 to stop after one match can be omitted if you anchor the pattern. And 
the return value doesn't matter since you're ignoring the substituted string.
