Talking of which, what is the present consensus on how to enumerate 
over vararg?

Considering:

local function test( ... )
        print( "print", #{ ... }, ... )

        for anIndex, aValue in ipairs( { ... } ) do
                print( "test", anIndex, aValue )
        end

        table.foreachi( { ... }, print )
end

test( "a", "b", nil, "c" )

print   4       a       b       nil     c
test    1       a
test    2       b
1       a
2       b
3       nil
4       c

The print() function recognizes the nil parameter. The length operator 
returns 4. foreachi() enumerates all the values. ipairs() stops at the 
first nil.

What gives?

Cheers
