Not sure I fully understand this...

The complexity of typeof is constant if either native __typeof__ or MSVC
trick (by Igor Chesnokov) is used.  In this case also no registration is
required.  In this mode BOOST_TYPEOF_NATIVE is defined.

If emulation is used, the complexity of typeof is (almost) linear,
registration is required, and BOOST_TYPEOF_COMPLIANT (probably should be
changed to BOOST_TYPEOF_EMULATION) defined.

Is this what you meant or did you have something else in mind?
