C++ wasn't `an attempt to mimic some of the concepts promoted in Smalltalk.'
It is the result of blending the Simula class concept into C in such a
way that C's low-level efficiency and general abilities and a system's
programming language wasn't impared.

The first use of C++ was for Simula-like simulations (what is called
process level simulation) with thousands of processes. The task
library that comes with the AT&T distribution supports such work
in a way rather similar to what is provided in Simula.
