Return whether the specified lhs and rhs have the same value.

bool
operator==(

requires (!NullableValue_DerivedFromOptional<RHS_TYPE>) &&
requires { { *lhs == rhs } -> NullableValue_ConvertibleToBool; };Return true if the specified lhs and rhs objects have the same value, and false otherwise. A nullable object and a value of some type have the same value if the nullable object is non-null and its underlying value compares equal to the other value. Note that this function will fail to compile if LHS_TYPE and RHS_TYPE are not compatible.
