From top of content.html, Lua 5.1.4 html docs:

"The reference manual is the official definition of the Lua language. 
[...] "


Thus, for what I may infer, it is also the official definition of the 
default libraries (I assume that in that sentence "language" refers to 
both core and libraries).

Therefore if io.lines returns a single function, that is the expected 
behaviour of any "conforming" implementation, as I understand it.

Cheers!
