template <class T>
struct is_default_constructible : public true_type-or-false_type {};
Inherits: If T
can be default-constructed then inherits from true_type,
otherwise inherits from false_type.
Type T must be a complete
type.
Compiler Compatibility: This trait requires
the C++11 feature decltype support
for full support. While there is some fallback code for cases where this
is not the case, the trait should really be considered broken in that case.
