Ok, now I'm totally confused I think :) Or rather classes work quite
differently from functions, I guess...

Maybe some example is better, lets take this:

class Bar:
  pass

I've got the following DUChain:
kdevelop(14055)/kdevelop (python support) Python::DumpChain::dump: "" New Context  "" [ (0, 0)  ->  (23, 0) ]   top-context
kdevelop(14055)/kdevelop (python support) Python::DumpChain::dump: "  " New Context  "Bar" [ (0, 0)  ->  (2, 1) ]
kdevelop(14055)/kdevelop (python support) Python::DumpChain::dump: "    " Declaration:  "<notype> "  [ "Bar::" ]   0x844ef20 (internal ctx 0x0 ) [ (0, 6)  ->  (0, 9) ] ,  defined,  0 use(s)

i.e. there's a Context with localScopeIdentifier "Bar" and inside that
the class declaration and following that would be the body statements.

Or should the Declaration be in the top context and there should be a
context just for the body with the localScopeIdentifier "Bar"?
