Subject: [Boost-users] [type_traits]: is_boost_optional?

Hi,

is there something in Boost.TypeTraits (or somewhere else) that allows
me to check if a type is a boost::optional?

I'd like to do something like this:

template<typename T>
typename enable_if<is_boost_optional<T> >, T::value_type>::type
foo(const T&);

Thanks and regards,

Roland
