The same idea was already proposed to optimize str%args and str.format(args). struct.unpack() does also compile the format into an optimize structure (and have a cache).

We may do something like Martin von Loewis's _Py_IDENTIFIER API: compile at runtime at the first call, and cache the result in a static variable.

It's not a tiny project, and I don't know exactly how to build a "JIT compiler" for getargs.c, nor how complex it would be. But it would speed up *all* Python calls, so any Python application.
