<div>Congratulations on merging the cell magics branch! This looks like it'll allow some really amazing stuff, but just having the timeit, prun, and cython magics seem worth the effort.</div><div><br></div><div>Speaking of `timeit` I noticed that it returns without execution if no setup code is given. For example,</div>
<div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div><div>%%timeit</div></div><div><div>2**2</div></div></blockquote><div><br></div><div><div>will return without execution. A simple change to the magics def seems to work on my system: <a href="https://github.com/tonysyu/ipython/commit/4f6b8aa607f6fa35fcf17387a8d248c56aedcc6f">https://github.com/tonysyu/ipython/commit/4f6b8aa607f6fa35fcf17387a8d248c56aedcc6f</a></div>
