Bug 9276 – regression(2.061): Forward reference error

Created attachment 1175 Repro test case. Compiles with 2.060, fails to compile with 2.061. run 'dmd parser' The test case is also added as an attachment. module declaration; import semantic, visitors, util; class Declaration{ mixin DownCastMethods!TemplateDecl; } class TemplateDecl: OverloadableDecl{ mixin Visitors; } module expression; import parser; import util; class Node{ mixin DownCastMethods!Declaration; } class Expression: Node{ } module hashtable;module parser; public import expression, declaration; module semantic; class Declaration{ mixin Visitors; } template Semantic(T) { private: struct { import hashtable; } } import visitors; class OverloadableDecl: Declaration{ } module type; import parser; class Type: Expression{ } // <- note to Walter. class BasicType: Type{ } module util; string _dgliteral(T...)(){foreach(t;T) return t.stringof; assert(0); } template DownCastMethods(T...){ enum x = _dgliteral!T; } module visitors; template Visitors(){ mixin Semantic!(typeof(this)); mixin DeepDup!(typeof(this)); } import type; template DeepDup(T) if(is(T: BasicType)){} template DeepDup(T) {}
