Go look at the original claim, the one that you responded to. "It's much easier to distribute C libraries than C++ libraries." Of course they can both call C libraries. All modern C++ compilers can too, not just cfronts. What almost no C++ compiler or C++ front can do is call a C++ library that a different C++ compiler or C++ front generated. (Unless they export function calls with C linkage, but that's not too helpful since the ostensible benefit of C++ is function overloading and subclassing and such, which you can't do at all between different compilers or fronts.) Hence, "It's much easier to distribute C libraries than C++ libraries." [snip rest of post that misses the point] Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
