The Ptolemy system has grown up with the C++ language, so it does not use all the latest features in the newest compilers or every nook and cranny of Ellis and Stroustrup's Annotated Reference Manual, because of unimplemented features or lack of stability of implementation. Instead, we focused on stability. Accordingly, Ptolemy can be built with a number of different C++ compilers. This means, for one thing, that templates are not used (except in the experimental IPUS domain). In addition, some features that do not work that well yet under g++, such as nested classes, are also avoided. Nested enumerations, however, are used in several places.
