1. Unnamed mixin
----
import std.stdio;

template Foo()
{
  int x;
}

struct S
{
  mixin Foo;
}

void main()
{
  writefln(__traits(allMembers, S));
}
----
Outputs [__T3FooZ] instead of the expected [x]

2. Multiple unnamed mixins
---
template Foo()
{
  int x;
}

struct S
{
  mixin Foo;
  mixin Foo;
}

void main()
{
  writefln(__traits(allMembers, S));
}
----
Outputs [__T3FooZ]. What's the expected output anyway? Could the name conflict be detected before the conflicted name is referenced?


3. Template alias
----
import std.stdio;

template Foo()
{
  int x;
}

struct S
{
  alias Foo!() foo;
}

void main()
{
  writefln(__traits(allMembers, S));
}
----
Outputs [foo __T3FooZ] instead of the expected [foo]
