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
Regardless of efficiency, it is always better to make variables as local as possible. 

However, it is also more efficient.
