[C++-sig] boost.python: modifying class getattr

[Julien Sylvestre]

Hello all,
    I'm trying to access the type structure for a c++ class exposed to
Python using boost.python, so that I can have ob_type->tp_getattro point
to a custom function instead of PyObject_GenericGetAttr (for those who
wonder why, it's a performance issue: with my current project,
PyObject_GenericGetAttr is always called first, fails to find the
requested attribute, and then __getattr__ is called on the wrapped
object, which returns the attribute. I get an extra PyString_FromFormatV
for each access to an attribute value, and this slows down my code by ~20%)

If I write:
object Foo_ = class_<Foo>("Foo", init< >())
      .def("__getattr__", &Foo::Foo_getattr)
      .def("__setattr__", &Foo::Foo_setattr)
...,

is there a way to modify the type object associated with Foo_ instances
so that instead of calling PyObject_GenericGetAttr when an attribute is
requested, Python calls a function
PyObject *
Foo_GetAttr(PyObject *obj, PyObject *name)
?

Thanks,
Julien.
