Re: [isocpp-lib-ext] LEWG(I) (Bi)Weekly review - P2510R0: Formatting pointers

I now officially can't tell when Victor will like a <format> addition or not.

Allowing locale-dependent printing of pointers in order to get a more
readable representation seems a hack to me. If the user goal is a
more readable pointer representation, we should be providing a direct
way to obtain it, not something that abuses the localization mechanism
to achieve it indirectly.
