Hi Stefan,

I saw this indexing method. I want to expose float* to python, so that
boost::python::object(float*,float*) is callable in c extension.
But here float* is not a class. If even I "typedef float* vector;", then
expose vector as following,
class_<vector>("Vec")
.def(vector_indexing_suite<vector>())
;
it will report a error."error: `float*' is not a class, struct, or union
type"
Could you tell me how to expose it?
Thanks.
