Commonly used

• std::enable_if
• std::conditional
• std::is_same
• `std::remove_const
  • Removes const qualifier from T
  • difference with const_cast? That does it on a particular variable instance, as opposed to making a modification on a type
• std::add_pointer<T>

Lots of modern C++ is around this.
