If the time is being spent in PyErr_Format, how far could you get adding
a dedicated function for creating AttributeErrors? Something along the
lines of:
PyErr_AttributeError(PyObject *object, PyObject *attr_name)
It would then be possible to modify AttributeError to have obj_type and
attr_name attributes (holding the type name and the name of the missing
attribute), so that any string formatting could be deferred until repr()
was called on the AttributeError instance.
Cheers,
Nick.
