What I want is something like this:

----
string className(in Object obj) {
     return obj is null ? "null" : typeid(obj).name;
}
----

...except I want it to work in CTFE. What is the way to do this 
in D?

Upon seeing this I just implemented typeid(stuff).name;

With any luck this will be possible in the next release ;)

Can this work using `stuff.classinfo.name` too ?
This is the same as `typeid(stuff).name`

Currently no. It's represented differently in the end tree.
