Prefixing inherited class's features

I have a deferred class BUFFER which I need two of in a
class such as:

class
  ONE
inherit
  BUFFER
  BUFFER
end

The problem is of course that every feature in each class
collides
with the other.

Is there an easy way to prefix or suffix every feature in a
class with
something such as "_bytes_" or
"_words_"?

I could just fully implement BUFFER in two separate classes
and then
use them as expanded instance variables but it would be nice
to be
able to use BUFFER without having to create two new classes
to make
the deferred class, BUFFER, effective.

Overlooked that.  "massive' only if "BUFFER"
is so - this may be quite easy.
