Missing information in the Lua 5.1 reference manual?
In the excellent
Programming in Lua Second Edition it talks about debugging coroutines (at the
end of section 23.1), and how all of the introspective functions in the debug
library accept an optional coroutine as their first argument. I can't find any

Have I just missed it, or is the manual missing that
