Provides compilation machinery similar to codeop, but with caching support so we can provide interactive tracebacks.

Parameters ---------- transformed_code : str The executable Python source code to cache and compile. number : int A number which forms part of the code's name. Used for the execution counter. raw_code : str The raw code before transformation, if None, set to `transformed_code`. Returns ------- The name of the cached code (as a string). Pass this as the filename argument to compilation, so that tracebacks are correctly hooked up.
