I am trying to get UnitName from the RTTI but have some problems:

Few questions now:
a) Why TypeInfo(TObject) <> TObject.ClassInfo?
b) Why TypeInfo(TPersistent) = TPersistent.ClassInfo?
No idea why but it is the same in delphi < d2010. Probably in d2010 it
depends on project rtti settings. And UnitName = '' in d2009 for classes with
no RTTI.
The implementation is probably the same: consult RTTI if present.
If it is not present, then return empty...
c) How to get TypeInfo of the class inside that class class method?
Probably no way except the using the same info which ClassType using.
So what is the best way to implement this UnitName method?
Still the question. Using RTTI and return empty result if it does not exists
or changing the compiler to write unit name near the class name?
Maybe generate partial RTTI for classes not in $M+ ?
