Just did a bit more thinking:

It would be good if we could support case-insensitivity in at least 
functions like
DUContext::findDeclararations, DUContext::findLocalDeclarations, 
PersistentSymbolTable::declarations etc. pp.

That way I could make uses case insensitive without the need to copy too 
much code. And I don't want to make the declarationbuilder save 
everything in lowercase, as then camelcase'd functions etc. would be 
all-lowercase after code-completion.
