Take the following code:

    template Seq(T...) { alias T Seq; }

    auto exec(alias F)() { return F(); }

    void main()
    {
        foreach (x; Seq!(0, 1))
            static assert (exec!(() => x)() == x);
    }

This will fail with "Error: static assert  (0 == 1) is false" on DMD64 v2.059.
