[self-interest] Kansas and Tcl

[Randy Smith]

Okay Albertina, I'll try to respond for you here: Self's GUI was never 
tuned to being like Motif or being fully brought up to address the 
construction of stand alone, single apps. Rather we were exploring the 
sense of a world in which many applications could be created and 
recombined. Nevertheless, our hypothesis has always been that the 
difficulties Ousterhout observes (the problem of bridging the direct GUI 
environment with a general purpose programming language) can be 
addressed. There are difficulties of course, and deep issues such as the 
fact that direct GUI assembly and modification is a different 
environment than the textual environment of the language's code.
