you're right, and the easiest way to get ride of W0233 false positive is
to skip YES object where this message is issued, as done by the patch
below. Getting warning for inference problem is harder since this
problem is tied to astng which shouldn't contain pylint specific code.
I plan to use the logging module at some point to allow astng > pylint
communication, but this is really not a priority for me at least, so...
