Issue ID: 16130 Summary: Disallow class template constraints from appearing after BaseClassList Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nob...@puremagic.com Reporter: bugzi...@digitalmars.com Currently, a Constraint is allowed both before and after the BaseClassList by the grammar: http://dlang.org/spec/template.html#ClassTemplateDeclaration http://dlang.org/spec/template.html#InterfaceTemplateDeclaration There is no purpose to the redundancy, and the 'after' syntax doesn't make much sense. The grammar rules: class Identifier TemplateParameters BaseClassListopt Constraintopt AggregateBody interface Identifier TemplateParameters BaseInterfaceList Constraint AggregateBody should be removed. I don't know how they ever got there in the first place. --
