I have heard mixed reviews of C++.  Yes it seems that it would be a
great productivity tool PROVIDING you have a 32Bit CPU and a compiler
with LARGE amounts of capacity (I've heard of people exhausting certain
limits on the 4.2BSD compiler on a VAX...).  Some of us still have to be
able to live with 16Bit processors (INTEL 8088/86/286) and some of us
even have to live in the small model domain (strictly 16 bit addressing
with split I/D).  Not everyone has a spare VAX in their basement (YET :->).
