Hi:
I write code like this
```D
class Base
{
int base;
}
class CC :Base
{
int cc;
}
auto cc = new CC;
//I want check cc object type is CC
if (typeid(cc) == typeid(CC)) // ok ==
if (cc.classinfo == AstAssignNode) //error
if (cc.classinfo == AstAssignNode.classinfo) // ok ==
```
They are both the same. Historically they were different
(ClassInfo was its own type different from TypeInfo_Class). I
would recommend typeid for future-proof code (it's possible,
however unlikely, that .classinfo at some point goes away).

Will it be the same if using "is", the reason is for function
that use "nothrow" attribute?
if (cc.classinfo is typeid(CC))
