[C++-sig] [pyplusplus] functions returning double&

[Benjamin Koerner]

How can one allow Py++ to handle member functions that return a reference to an immutable type?

For example this X::getval function:
class X{
double xval;
public:
  double& getval(){return xval;}
}; 

I don't care about the reference. All I need is the double value, which is only used as an r-value. Can one use a call policy in this situation, or does one have to write custom wrapper code?

Regards,
Bennie
