I'm going with exc_clear(), since 'clearing' seems to be the verb most
people are using when talking about the action it performed.

Implementation question: I'm planning to reuse the reset_exc_info function
defined statically in ceval.c.  Which of these options do you prefer:

  1) Just remove the static declaration from reset_exc_info and add the
     prototype as an extern declaration to sysmodule.c.

  2) Remove the static declaration from reset_exc_info and add the prototype
     to an include file.  If so, which include file is the most appropriate
     place?

  3) Move the implementation of reset_exc_info out of ceval to another, more
     public, file.  If so, which one?

I ask only because I usually submit bug fixes and minor changes, and am not
familar enough with this part of the Python development culture.

This is what I do, though I have a nice 10 line comment in the source to
ward off much squinting and head scratching from our junior developers.

Thanks,
