Well, we're working on an Interlisp-D/Symbolics/Smalltalk -inspired Modula-2
environment on the Sun workstation. The system includes an interpreter and
an incremental compilation system. In our environment programs can build
data structures which are programs (or pieces of programs) and send them off
to the intepreter. The system is based on using a special data structure for
representing Modula-2 source code. This data structure can be manipulated using
library modules available to toolmakers. The editor is pretty "intelligent"
because it works on a higher level than text only. You can view module dependencies
and stuff like that, and it is easy to write new tools which manipulate/write
programs. We have built an o-o database server for managing all the data,
and the user interface is NeWS-based.

While not extending Modula-2 in itself, we're trying to provide a dynamic,
LISP-inspired environment for Moduleans. The first release will target the
embedded systems market, so the environment does support "Modula-2 -- the
fast systems language".
