Smalltalk/ROSE-like prog. environment?

[Bjoern Giesler]

Hi,

I have a dream... :-)

I'd like to have a programming environment that allows you to do graphical
OO design (UML, ROSE-like) with access to all classes a project consists of
(Smalltalk-like). This thing would allow the programmer to graphically
design class interfaces and interactions, and edit method source code on a
per-method basis. I.e. no editing-around in large .py files but working just
on the job at hand.

This would have a couple of other nifty features: A test mode in which an
exception is presented to the user in a dialog box that allows modification
of the code _while the program is running_ (this could be done with
continuations, I believe) and stuff like that.

This is a very hazy notion that has been floating around in my head for a
while. I believe that Python would be the ideal language for this kind of
application. Does anybody know of such an environment?

If not, I'd like to give it a shot. Anybody have any ideas or want to
collaborate with me?

Regards,
