Jim,
actually, this IS impossible, for a limit of Boost.Python. The
explanation is into the FAQs of the Boost.Python documentation.
Basically it is not possible to develop an l-value converter, so it's
not possible to solve this problem. The author of Boost.Python
explains that for solving this problem a complete review of the
library is needed (and I hope he will do it so that in the future that
feature will be available).
Bye,
