Possible improvements include:
Implementations of the Singleton design pattern are frequently
needed; the type module alone requires three instances! Therefore
a template to generate such singletons is desirable. There are two ways
to address this issue: tailored to type (directly in
src/type/builtin-types.*), or in a completely generic way (in
lib/misc/singleton.*). See Modern C++ Design, for a topnotch
implementation.
When reporting a type, one must be careful with recursive definitions
that could produce never ending outputs. The suggested simple
implementation ensure this by limiting the Named-depth (i.e., the
number of Named objects traversed) to one. Another, nicer
possibility, would be to limit the expansion to once per
Named.
tcsh is up and running. You might want to use it to implement a
GUI using Python’s
Tkinter.
