Re: Odd behaviour with multiple return values and varargs

["John Calsbeek" <nexuapex@...>]

Problems with multiple return values not getting truncated:

 

function maybeval()

    if not errorCondition then

        return someValue -- bad things happen if this is return someValue, nil

    else

        return nil, "error message"

    end

end

 

-- If the return was someValue, nil there are problems

-- but if the return is specified as above it works fine

-- up until an error. Hopefully the programmer wasn't

-- expecting it to just pass nil to somefunc, 'cause it won't.

somefunc(maybeval(), "some other value")
