But "python" seems rather an intuitive way of doing it.  The existing behavior is quite surprising and unintuitive, because it accumulates an entire multi-line string without any parsing, and then hands it off all at once to Python.  I see no reason to preserve that behavior if we have a normal Python interactive interpreter loop.  That loop does everything the existing thing does and far more/better, so it should replace the old behavior.

For example, if you commit a syntax error, the existing machinery doesn't tell you until much later, when you say "end".  The interactive interpreter will tell you at the time you make the error.
