   PythonCompiler is the main class to access the Python compiler.

   This class is used for both interactive (.evaluate()) and non-interactive
   (.get_llvm2()) compilation. The methods return diagnostic messages (errors,
   warnings, style suggestions, ...) as an argument. One can use
   Diagnostic::render to render them.

   One can use get_asr2() to obtain the ASR and then hand it over to other
   backends by hand.
