 A simple, header-only cpp library implementing smart pointer type traits.  
 You can easily compile your code diffrently depending on which pointer-type is used.  
-You can detect inheritance too and you won't have trouble with const, volatile qualifiers.  
+You can detect inheritance too and you won't have trouble with const, volatile qualifiers.
+It also contains member detections. (SFINAE based)
 
 Type traits are generally used for static assertions and static polymorphism. (C++ 17 if constexpr)  
 However, the standard library's type traits do not support smart pointers, and do not detect inheritance.
