As far as I can tell from the docs, you need to pass true in the
NoProxy parameter slot of the vector indexing suite.  But I'm not an
expert on the indexing suite stuff, which is why I've been trying to
get Joel and Raoul to answer this.  

Incidentally, Joel, NoProxy is listed twice in the template parameters
for indexing_suite, and green was meant to be used in the
documentation for class_<...> only to indicate that template
parameters could appear in any order.  Unless indexing_suite has the
same property, you should probably use black.
