I don't know if it's 'commonplace', but that's something I only do when
I absolutely want to protect a given attribute of a base class from
being accidentally overriden by a derived class. Else I use the usual
convention ('_name' => implementation, 'name' => API), and assume users
of my code will read the documentation (or the source FWIW) before
subclassing. Note that since 'users of my code' are mostly my coworkers
and I, this is a quite sensible assumption !-)
