This would happen if the overloads are computed
by metaprogramming instead of being hard-coded
into the source.

I would argue that overloaded_function should be
a fusion sequence even without knowing any specific
use cases.  If something looks like a container, I
can pretty much guarantee that sooner or later,
someone will want use algorithms on it.
