   struct alignment_of : public __integral_constant<std::size_t, ALIGNOF(T)> {};
  
__inherit Class template `alignment_of` inherits from 
`__integral_constant<std::size_t, ALIGNOF(T)>`, where `ALIGNOF(T)` is the
alignment of type T.  

['Note: strictly speaking you should only rely on 
the value of `ALIGNOF(T)` being a multiple of the true alignment of T, although
in practice it does compute the correct value in all the cases we know about.]

__examples

[:`alignment_of<int>` inherits from `__integral_constant<std::size_t, ALIGNOF(int)>`.]

[:`alignment_of<char>::type` is the type `__integral_constant<std::size_t, ALIGNOF(char)>`.]

[:`alignment_of<double>::value` is an integral constant 
expression with value `ALIGNOF(double)`.]

[:`alignment_of<T>::value_type` is the type `std::size_t`.]
