It seems you are not only questioning the hack I proposed using the NV field, but the entire idea of returning C objects to perl as blessed references to SVs holding the pointer value (in the case as an IV), correct? But isn't that a rather common approach? I just checked the JSON::XS library which IMHO is one of the best working CPAN modules. It goes even a step further. It returns an entire native C JSON struct byte-for-byte as a PV string ... and the typemap INPUTs it as the SvPVX pointer. - the (char *) pointer to the Perl string only cast as a JSON*. Isn't that also pointer pass-around and very-dangerously exposing the C-library environment to the Perl environment, ?
