1. Looking at source code I've noticed a lot of global variables. lua-nginx-module complains on them, offering to consider to make them `local`. 2. Upon parsing it keeps spaces in front of cookie names 3. Cookie values with `=` signs in them being parsed incorrectly. 4. Strange (for me) format of return values 5. Method names with `2` at the end? Why? 6. Probably something else...
