A mixin template declaration needs to have parentheses following the name. If the parentheses are empty, it should be valid to omit them entirely. Grammar changes: TemplateMixinDeclaration: + mixin template Identifier TemplateParameters[opt] Constraint[opt] { DeclDefs[opt] } - mixin template Identifier TemplateParameters Constraint[opt] { DeclDefs[opt] }

I don't think it's worth it to change the grammar for such a marginal gain in writability. Is there any reason for this request ?

Just a random thought. Laziness is the main driver.
