 \subsection{Optimizations\label{opts}}
 
+Several of the optimizations were developed at the NeedForSpeed
+sprint, an event held in Reykjavik, Iceland, from May 21--28 2006.
+The sprint focused on speed enhancements to the CPython implementation
+and was funded by EWT LLC with local support from CCP Games.  Those
+optimizations added at this sprint are specially marked in the
+following list.

+\item Function calls are now faster because code objects now keep

 \item The CPython interpreter is still written in C, but 
 the code can now be compiled with a {\Cpp} compiler without errors.
