Huh, yeah. We'd have to go one way or the other on that, and neither of those are what you intend. Not that being explicit is always a bad thing: $val = some_cond() ?? ($arg1 // $arg1_default) // ($arg2 // $arg2_default) And I question your notion of "highly useful" in this case. Still, it is probably linguistically not a good idea to overload // like that. > > > ?? !! ain't bad either. > > It's definitely much better that sabotaging the (highly useful) // operator > within (highly useful) ternaries. I guess the thing that I really think is nice is getting :: out of that role and into the type-only domain. Luke
