Yes. Originally one could not use the "mixin" keyword in front of a 
template. There was no difference between mixin templates and non-mixin 
templates, on the declaration site. Later the language was changed to 
allow to put "mixin" in front of a template. That restricted all mixin 
templates to only be used as mixin templates. It's still possible to 
mixin non-mixin templates, most likely to avoid breaking existing code.
