<p dir="auto">One of the great features of IPython is that you are able to embed it in a currently executing program <code class="notranslate">IPython.embed()</code> so you can muck around with the current state at that point.  This would be a great feature to support with the new REPL.</p>
<p dir="auto">Debugging code is currently print() based. This isn't a particularly great solution.</p>

(My fault for bringing it up)</p>
