Because typeid(this) gives the same exact thing.  A long time ago, there  
was a separate Classinfo type.  But it has been merged into TypeInfo.

It was determined also that the most useful thing to return from typeid  
was the runtime TypeInfo, since you could always get the static typeinfo  
by doing typeid(typeof(x)).

TBH, I'm not exactly sure that classinfo is officially deprecated, but I  
don't think it appears anywhere in the docs.
