--- Comment #7 from Iain Buclaw <ibuclaw at gdcproject.org> ---
Related test still fails though.

struct S10666
{
    int val;
    ~this() {}
}


void foo10666(S10666 s1)
{
    // Error: s1 has scoped destruction, cannot build closure.
    auto f1 = (){ return () => s1.val; }();

    enum r1 = __traits(compiles, {
        auto f1 = (){ return () => s1.val; }(); 
    });
    static assert(!r1); // Error: static assert:  `!r1` is false
}
