An example in [dcl.init.list] p6 says that "assuming that the implementation can construct an initializer_list object with a pair of pointers". However, it seems unclear in the example itself whether the corresponding constructor can be exposed to users.

Presumably, the additional constructor shouldn't be public since [initializer.list.syn] doesn't show it. Should we clarify this in the example?

(The pointer-pair constructor is public in MSVC STL. But I guess such implementation divergence is just because of some restrictions in MSVC and no LWG issue is needed.)
