You're right, a per-namespace solution is possible. I don't think it can
be done in general, though (i.e. for all std::pairs of iterators in one stroke).

I'm not familiar with BGL - are the iterator types in question defined
in a namespace under the library's control, or could they be user-provided
types (in which the case the user would have to put the begin()/end()
in their own namespace)?
