You only need row polymorphism if you want full type inference. You can get away with width subtyping with bounded parametric polymorphism if you are willing to give up on inferring all types. Examples: Go, TypeScript, Flow...

Actually the "meat" of the course starts on unit 1, unit 0 is more of a recap of where Lua comes from and where it is used. :)

LuaForge's ftp server is broken since the big LuaForge crash a few months ago, so those pages are badly out of date. Browse http://github.com/keplerproject for more recent information.
