Hey everyone,
Would someone please explain to me the implicit cast rule that prevents the following from compiling, and/or if there is a way around it?
It's standard behavior of static_cast 5.2.9 paragraph 2. If you did the conversion implicitly instead of explicitly with static_cast, then the boost::optional constructor that is causing you trouble would not be considered (since it is explicit).
I can tell what is happening; it would seem that the implicit cast rule selects the optional() constructor before it even looks at my more specific cast operator. I'm just confused about why this should be, since I see no reason why constructor casts should be prioritized over operator casts. Is this just the way it is, a GCC quirk, something I'm doing wrong, etc?
