I'm not sure if there are many others who would like this, but I am looking for a default argument "User roles from logged in user" similar to existing "User ID from logged in user".

I have a "notice" content type with a role field "audience" so administrators can post notices to either users with the "staff" or "customer" role. I didn't want to go down the content_access route so I'm just using a view argument to filter the results.

Currently using a PHP argument.

$account = $GLOBALS['user'];
return implode('+', array_keys($account->roles));

Like I said, not sure if there is a big enough need for this feature, so if not at least here is a reference to my example PHP argument.
