	I didn't know that it's better to redeclare them instead of just 
reusing. I wonder if it is valid for chunks too:

while <condition> do
  local _,_,a,b = string.find(...)
end

local _,a,b
while <condition> do
  _,_,a,b = string.find(...)
end

	According to you, the first is better than the second, right?

	I don't. I also use it very often, but I had to show him possible 
alternatives :)

	I also remember that discussion ;)

Thanks for the tips,
