Arguably, to be compatible with code that does not know anything about boost, in the spirit of ADL, the following lower_bound should redirect to partition_point( CustomIt, CustomIt, pred):

using std::lower_bound;
CustomIt itA, itB;
lower_bound( itA, itB );

Do we agree that this is how the client side should work?

The only way to achieve that, as far as I can see, is to implement a lower_bound for each and every iterator that defines its own partition_point. Or do you have an idea?
