It's possible to have an instance variable and a local variable with the same name.
According to Marco's idea, those would be qualified differently: className.x vs className.funcName.x, but he recently provided an example where that is ambiguous.
Also it would be a problem for symbols declared inside anonimous members.
In general, I like symbol location ("file.d:50:7"). It should always be available to the tool which uses API.
