Oct 22, 2020 at 9:22	comment	added	user377672		@rwong I've seen people radically change styles overnight like `(2==x)` over `(x==2)` for expressions I've always been a bit more stubborn than that, favoring whatever seems idiomatic when possible and "natural" until I can't make a good argument for it anymore. But the namespace and ADL issues were enough after multiple bugs, not one, for me to favor using directives and declarations. I don't think we can avoid being implicit here. I might even push that using directives/declarations are more explicit because of the existence of ADL/Koenig Lookup.
