If I may jump in... At Lockheed's AI center we do alot of high level
prototyping. We usually use TCL for power end users to customize and
extend a given tool. In almost all cases it is sufficient to use a
standard text entry widget for this purpose.
If we used python instead (because it's a better language) we would have
to develop a variety of features to handle python's tab structure. Futher
more, those features would have to be added to each and every prototype
that we develop (extra overhead). Futhermore, the editing features of
a standard text widget are more of less universal and well understood.
(delete, return, tab, space, up, down, etc.) However, the additional
editing features required by python (mainly block indent/unindent)
are not universial. (Was that Meta-x block-indent or command I or what).
This, unfortunatly, means that adding end user code is not as intuitive
or requires extra work by us to handle pythons unique differences (like
a graphical menu etc.)
There are other reasons why we still have yet to shift to python. However,
the largest reason we still use Tcl over python is python's tab block
