Hi Christoph.

> Minimality might be a general goal for sustainable software development

Of course! But I gave that comment for a different reason. The EmergencyEvaluator is the last resort for recovery in the interactive system. We should carefully choose and design the amount of features to keep it as robust as possible. The less features, the better.

More fancy fallbacks for Morphic are the MVC debugger or the Squeak Shell. :-) Just install them as your parent project.

Minimality might be a general goal for sustainable software development :) I just wanted to avoid to repeat myself.

Hi Christoph,

note that the implementation of Transcripter should be as minimal as possible. That new "clear" command is fine, I guess. :-)

> In TranscriptStream, #showln: prints the newline first as well

I added that to TranscriptStream to make sure that even the first call to #showln: is on an extra line, regardless of its previous contents.

Best,
Marcel
