Reduced Phobos away:

void main() @safe
{
    assert(identity(2) == 2); /* fails; should pass */
}

struct Map(alias fun)
{
    int front() @safe { return fun(); }
}

int identity(immutable int q) pure nothrow @safe @nogc
{
    int getArg(int b) @safe
    {
        return b;
    }
    return Map!((int b = q) => getArg(b))().front();
}
