From Bios.lua


function print( ... )
	local nLinesPrinted = 0
	for n,v in ipairs( { ... } ) do
		nLinesPrinted = nLinesPrinted + write( tostring( v ) )
	end
	nLinesPrinted = nLinesPrinted + write( "\n" )
	return nLinesPrinted
end

ipairs goes from 1 to n as long as every index from 1 to n exists. Since 3 is nil. ({…})[3] doesn't exist. So ipairs will loop for 1 and 2, and stop.
