Are you inclined to think the source code of Tcl/Tk is where to look,
or do you think it is how Python's wrapper, tkinter,  implements
Tcl/Tk is where I should look?  I've been trying to research this
online and have been unsuccessful so far -- not quite sure how to
phrase an effective set of search terms.  I did come across that the
scripting language, Tcl, seems to have its own interpreter mode, so
your initial comments may be spot on if this was the behavior being
sought up front by Tcl itself.
