           Summary: regression(head): template mixin contents mixed in
                    multiple times
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: timon.gehr gmx.ch

To reproduce: dmd expression.d

// expression.d:
import semantic;
template Visitors(){ mixin Semantic!(typeof(this)); }
class Node{    mixin Visitors; }
class Expression: Node{ }
class BinaryExp(TokenType op): Expression{ }
// ---

// semantic.d:
import expression;
enum TokenType{Dot}
template Tok(string type){enum Tok=TokenType.Dot;}
template Semantic(T) { invariant(){ } }
template Semantic(T) if(is(T==BinaryExp!(Tok!"."))){ }
// ===

Output with dmd from head:
semantic.d(4): Error: function
expression.Node.Visitors!().Semantic!(Node).__invariant more than one invariant
for Node
expression.d(2): Error: mixin expression.Node.Visitors!().Semantic!(Node) error
instantiating
expression.d(3): Error: mixin expression.Node.Visitors!() error instantiating

This worked with DMD 2.060. (I assume that the bug was present before, as I
have had similar issues before, and it surfaces because the analysis order is
different.)
