I usually trap these things with assertions; from assertions to
exception the way is not too long (maybe there is something in boost to
make them a little less obtrusive)

Better sort off issues now before getting too committed... for example
did you look into Boost.Python? it seems to correctly support the
problem at hand
but maybe totally sucks for other stuff XD
