Can't refer you to a paper offhand, but look up papers on
component-based programming. Anecdotal experience suggests that for a
large, non-trivial system, OO's main claim to fame: inheritance,
hinders rather than promotes code reuse. People end up subclassing
stuff all the time, leading to a zillion subclasses of a base class. A
more useful facility is C++ template like solution which is really a
module that can be applied to any type. This is the only real "OO"
feature that contributes to productivity which Limbo lacks. All the
other useful properties of OO such as encapsulation, data abstraction
etc. are available in Limbo in a much more efficient package than more
traditionally OO languages.

Maybe one of the developers can comment more authoritatively on why
Limbo is not OO in the traditional sense.
