[Python-ideas] external editor commands in python REPL

[David Mertz]

There are several external tools that "compete" in this space already.  For
example IPython and BPython (take a look at
http://wiki.python.org/moin/PythonEditors#Enhanced_Python_shells) for
descriptions of other ones also.  As well, a good number of text editors
have the capability of incorporating a Python shell within them, which is
kind of the "same thing inverted".

Rather than enhance the deliberately simple standard Python shell, I would
recommend using one of those 3rd party tools (or developing your own if you
see something missing in them).
