Well, I recently did a development contract for Mentor, and the RFQ gave me
the choice of doing the library binding and diagnostic GUI in either Tcl or
Python.  Naturally, I chose Python (and wxPython), and both the client and
I are quite happy with the result.

(Actually, I did a Tcl binding for them as well, and just writing the text
scripts reinforced my dislike for it...)
