I am looking for a code documentation tool like PasDoc that supports the Delphi 2007 syntax, in particular nested types. I checked PasDoc and DelphiDoc but they do not support it.

To make overall support/development life easier (and to bring...

According to the implementation of TObject.ClassType, the first 4 bytes can be explained as a pointer to the object's TClass metadata. Anyone know what the other 4 bytes of overhead are there for?
