Normally I rely on this definition:

feature .. builds new types from old ones 

That matches my intuitive expectations. I.e. plain 'extern' is a 
storage class because for `const int x; extern int y;` type of y 
is still plain into but x is const(int)

@safe functions do have distinct type thus I'd expect it to be 
type qualifier/constructor. However D seems to use different 
classification that isn't documented anywhere.
