template this and traits getOverloads issue.

[Alex Parrill via Digitalmars-d-learn]

Alternatively, you can use a static method and pass in the 
instance.

Note that `new B` will print A's members twice, because A's 
constructor is always called and `__traits(allMembers, B)` 
includes A's members.

import std.stdio;

mixin template Bug()
{
     import std.traits;
     static void bug(T)(T t)
     {
         writeln(">", T.stringof);
         foreach(member; __traits(allMembers, T))
             foreach(overload; __traits(getOverloads, T, member))
         {
                 auto dg = &overload;
                 writeln(member);
         }
     }
}

class A
{
     mixin Bug;
     this(){bug!A(this);}
     void foo(){}
}

class B: A
{
     this(){bug!B(this);}
     void bar(){}
     void bar(uint a){}
}

void main(){
     new A;
     new B;
}
