[cfe-dev] [libc++] Why doesn't libc++ define std::vector<bool>::const_reference as bool?

[Mikhail Maltsev via cfe-dev]

Hi. According to the C++ Standard (section [vector.bool]),
std::vector<bool>::const_reference should be defined as bool. libc++
defines it as std::__1::__bit_const_reference<std::__1::vector<bool,
std::__1::allocator<bool>>>]. Is this divergence from the standard
intentional? If it is, what is the purpose?
