Code checker and underscores in variable names

Hi all,

Just upgraded to latest version 2.2.8 build 2013071300 of Code checker on my moodle 2.5 local test site. Under ECLIPSE I have installed the PHP CodeSniffer, based on Moodle's codechecker.

Now I notice a lot of warnings about not using underscores in variable names.

e.g. Variable "quiz_reordertool" must not contain underscores.

In our add-ons, should be care and start removing all those underscores?
