RE: Forwarding N Return Values

["Ashley Fryer" <lua@...>]

I didn't see any replies, so here's another try...

This code:

function returns_two() return 42, 43 end
function accepts_two( a, b ) print( a, b ) end

accepts_two( returns_two() )

Outputs this:

42   nil

Instead of this:

42   43

I think this is "by design" and has something to do with "return value
adjustment" per section 4.6.8 of the manual.

Question: Is there any way to use this syntax without resorting to
intermediate variables?

Question: Can this syntax be allowed for future versions?

TIA,
ashley
