XXX not sure what to make of this - -Not trivially. Python's high level data types, dynamic typing of objects and -run-time invocation of the interpreter (using :func:`eval` or :func:`exec`) -together mean that a naïvely "compiled" Python program would probably consist -mostly of calls into the Python run-time system, even for seemingly simple -operations like ``x+1``. - -Several projects described in the Python newsgroup or at past `Python -conferences <https://www.python.org/community/workshops/>`_ have shown that this -approach is feasible, although the speedups reached so far are only modest -(e.g. 2x). Jython uses the same strategy for compiling to Java bytecode. (Jim -Hugunin has demonstrated that in combination with whole-program analysis, -speedups of 1000x are feasible for small demo programs.
