(I find it more intuitive than `for from, match1, match2, to`)

function tweak(f)
    return function()
       local a,b,c,d = f()
       if d then return a,d-1,b,c end
    end
end

S="The quick brown fox jumps over the lazy dog"
pat="()(%S+)%s+(%S+)()"

for from,to,match1,match2 in tweak(S:gmatch(pat)) do
    print(from, to, match1, match2)
end
What if I want to be able to stick any pattern on it without having to write a new one every time?
