No, it is not clear to me why you think that there a difference. Can
you please list your arguments? For example, why is there a difference
with respect to Boost.Algorithm so to be specific.

My understanding is that you'd answer:
1) Because Boost.Algorithm all_of is useful but Boost.Local local
functions are not.
2) Because Boost.Algorithm all_of uses exactly the same API as C++11
while Boost.Local uses macros.
Is my understanding correct? Is there more?

Thanks a lot.
