2 # Parent class of everything that can live in a MethodTable.
4 # When calling an Executable, first the primitive slot is checked and executed
5 # if it exists. If execution of the primitive is successful, the value is put
6 # on the stack, and execution of the method is finished. If unsuccessful or
7 # absent (only in the case of a CompiledMethod) a MethodContext is created and
8 # activated (see MethodContext).
