This seems to be wrong. select (1, ....) should only return the first
argument, not both. I'm wondering why select (2, ....) works as
expected. I must admit that I couldn't find any specs for select(),
it just appears in some examples in the Lua book.
The reference manaul is separate. You can buy it on paper, but
much easier is the free online version, because it conveniently
starts with an index right after the toc:
http://www.lua.org/manual/5.1/
From there:
select (index, ยทยทยท)
If index is a number, returns all arguments after argument number
index. Otherwise, index must be the string "#", and select returns the
total number of extra arguments it received.
Best wishes,
