>From §2.5.7 of the Lua 5.1 reference manual, which is about table constructors:
"If the last field in the list has the form exp and the expression is
a function call or a vararg expression, then all values returned by
this expression enter the list consecutively (see §2.5.8)."

The message to take away from this is that things are truncated to
exactly 1 result iff they are not the last thing in an expression
