I've a problem with templates as return types. As you can see in the screenshot function signatures get colored in "TemplateTypeParameter" class if i use a template variable as return value. Without a template all works fine.

Also i have 3 different collorings for std::string in the image (green:yellow, green:green, blue:blue).
