I tried to search the meaning of "tupleof" and "classinfo" properties, so I went to the digital mars page, Language, Properties, but they are not there. So I had to search using the "search" field, found the meaning of tupleof but still didn't find where "classinfo" is specified. Should these properties be listed as well in that page?

Your right.   I found this but it gives little information.

http://www.digitalmars.com/d/phobos/object.html

Its actually part of the run-time library Phobos:  You can look it up in the object.d file.  ClassInfo looks like this:

class ClassInfo : Object
{
    byte[] init;		// class static initializer
    char[] name;		// class name
    void *[] vtbl;		// virtual function pointer table
    Interface[] interfaces;
    ClassInfo base;
    void *destructor;
    void (*classInvariant)(Object);
    uint flags;
    //	1:			// IUnknown
    //	2:			// has no possible pointers into GC memory
    //	4:			// has offTi[] member
    void *deallocator;
    OffsetTypeInfo[] offTi;
}


I added a section to the comments section for that page:
http://www.prowiki.org/wiki4d/wiki.cgi?DocComments/Phobos/Object#section6

Perhaps someone would like to expand it.

(Tip its always a good idea to check out the "Comment" section, although in this case it wouldn't have helped.)

PS
I wish DMD's searching of help was a little friendlier.  I'm surprised you where able to find anything.
