Inherits std::__or_<... >::type.

🦋 DETAILED DESCRIPTION 🦋

template<typename _Tp>
    struct std::experimental::_Has_addressof< _Tp >

okay so this is the trait that detects the presence of an overloaded unary operator&. no cap, that's literally its whole thing 🌈

Practically speaking — and this is the part where it gets cute — it detects that operator when it's called on a const-qualified lvalue. The vibe check example being declval<const _Tp&>().operator&(). so like, const lvalue specifically, not just any old object, iykyk 💜

Definition at line 162 of file optional. ⭐ (yes, the file is literally named optional, iconic)
