Re: Odd behaviour with multiple return values and varargs

["Duncan Cross" <duncan.cross@...>]

When an _expression_ evaluates to multiple values, all but the first will be discarded if the _expression_ is part of a list but is not the final element in that list. It's the same in table constructors.

Okay, so I'm obviously missing something with this.  Can anyone explain the behaviour from this:

 

function test1()

    return 1, 2

end

 

function test2()

    return 3,4

end

 

print(test1(), test2())

 

> 1    3    4

 

I would have expected it to output 1    2    3    4.  Why doesn't it?
