I know I'm a PITA and everything, but would you mind explaining this:

kdevelop(31278)/kdevelop (cpp support) CPPInternalParseJob::run: ================== duchain ==================
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "" \ TranslationUnit [( 1 ) (0, 0) ] ""class Foo { } ;""
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| " \ SimpleDeclaration [( 1 ) (0, 0) ] ""class Foo { } ;""
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| | " \ ClassSpecifier [( 1 ) (0, 0) ] ""class Foo { }""
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| | | " \ Name [( 2 ) (0, 6) ] ""Foo""
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| | | | " \ UnqualifiedName [( 2 ) (0, 6) ] ""Foo""
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| | | | " / UnqualifiedName [( 3 )  (1, 0) ]
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| | | " / Name [( 3 )  (1, 0) ]
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| | " / ClassSpecifier [( 5 )  (2, 1) ]
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "| " / SimpleDeclaration [( 6 )  (3, 0) ]
kdevelop(31278)/kdevelop (cpp support) DumpChain::visit: "" / TranslationUnit [( 6 )  (3, 0) ]
kdevelop(31278)/kdevelop (cpp support) DumpChain::dump: "" New Context  0x83068c0 " "" " [ "" ] [ (0, 0)  ->  (0, 0) ]   top-context
kdevelop(31278)/kdevelop (cpp support) DumpChain::dump: "  " ==import==> Context  0x864bcc8 " "" " [ "" ] [ (0, 0)  ->  (3, 0) ]   top-context

Thats from a simple "class Foo {};" apparently. What I don't quite
understand here is that there's no Declaration dumped by DumpChain,
while apparently it got created:

kdevelop(31278)/kdevelop (cpp support) ContextBuilder::buildContexts: built top-level context with 1 declarations and 0 included files

PS: Thanks for answering all these noob questions, I owe you a beer or
two.
