node for parse-trees, representing primitive code
Primitives are currently not supported by the compiler
- if you want a primitive, you must use the stc-compiler and
link a new smalltalk.
In the future, methods with primitives will be passed to stc and
the resulting binary be loaded into the image (also a limited set
of numeric primitives could be implemented for more ST-80
compatibility - if there is a need).
