[C++-sig] CallPolicy for operators

[Michael Wild]

Hi all

Is there a way to apply a CallPolicy to operator definitions? In
particular, I'm interested in the inplace operators (+=, -=, *=, /= and
friends).

To give a bit more context: The library I'm trying to wrap exposes some
static const objects. So far, I have been able to wrap modifying
function by having a registration facility for these static const
objects and a custom CallPolicy that raises an AttributError when one
tries to modify one of the registered objects.

One option I see is to directly define __iadd__ etc. instead of using
the built-in convenience operators. However, I'm not sure whether that
has unintended side-effects. I haven't completely understood the
operators implementation in bp, but it looks fairly involved.


Thanks

Michael
