Subject: [Boost-users] MPL newbie : what is the difference between mpl::true_ and true_type

I'm a newbie for both boost and MPL. My question is regarding about the
differences between mpl::true_ and true_type. While from my point of
view they are both structure of constant boolean. Even in the
implementation true_type is derived from mpl:true_. So why we need both
data structure instead of only single one. When we should use mpl::true_
instead and true_type and vice versa
