IPython (Jupyter) cell magics and cross-language interaction
<p>In a normal ipython notebook or repl session, I can refer to previously-run cells using the _# notation. </p>

<p>However, this is not possible when using cell magics such as %%perl or %%bash because these cells do not have entries in _oh. Nor can I find a way for any two languages to refer to values in the other's namespace.</p>

<p>Does anyone know a way to move information between cells that use different languages, other than using an external file?</p>
