This code fails with message dmd: aliasthis.c:100: virtual void
AliasThis::semantic(Scope*): Assertion `t' failed.

import std.stdio;

struct Tuple(T...)
{
    alias T expand;
    alias expand this;
}

template Foo(alias A,alias B)
{
    static assert(is(A == Tuple!(1,int,"foo")));
    static assert(is(B == Tuple!(2,double,"bar")));
    static int dummy = 0;
}

void main()
{
    alias Tuple!(1,int,"foo") A;
    alias Tuple!(2,double,"bar") B;
    writeln(Foo!(A,B).dummy);
}
