Hey.. I don't have much time right now, I am working hard for my speech I will 
hold tomorrow, and then I will be on vacation for a week, so don't expect too 
much input from me in that time. :)

But generally, I don't see how we could allow case-insensitive search in the 
duchain. That is simply not possible in any even half-efficient way, as the 
searching is done through the IndexedString indices.

So I guess the best way would be: Create some additional declaration type, 
maybe a template like TemplateDeclaration, where you can attach an additional 
"pretty" string to each declaration. That would be the 'with case' string then 
in php, while internally everything would have a lower-case identity.

Then before printing something to the user, you will have have to "prettify" 
it before showing by using the 'pretty' string instead of the identity, much 
like the C++ support does (It leaves out template default parameters, resolves 
typedefs when necessary, etc.).
