This is supported by Boost.Python:
http://www.boost.org/libs/python/doc/overloading.html

Having said that, I always get lost with the casts.
Here is an alternative:

SgOps has a method isCentric with two overloads. To bind
this to Python define free functions:

  bool SgOps_isCentric_0(const SgOps& sgo) {
    return sgo.isCentric();
  }
  bool SgOps_isCentric_1(const SgOps& sgo, const Miller::Index& H) {
    return sgo.isCentric(H);
  }

Bind these to Python:

    py_SgOps.def(SgOps_isCentric_0, "isCentric");
    py_SgOps.def(SgOps_isCentric_1, "isCentric");
    py_SgOps.def(&SgOps::isOriginCentric, "isOriginCentric");
    
This third binding is just to show the difference to "normal"
bindings.
