As I said on IRC: I don't think this is 'correct', as boost and tr1 are two
disjunct sets of APIs. I don't know the details of how the converters work,
but I'd guess just declaring the above get_pointer() function so it makes
its way into the overload set seen when the compiler instantiates the conerter
harness should be enough.

If it isn't, a (simple, minimal) test case may be a good idea. :-)
