struct Mutexed
{
    auto acquire ()
    {
        return Lock (this);
    }
    alias acquire this;

    struct Lock
    {
        Mutexed* source;
    }
}
void main ()
{
    Mutexed x;
}


if auto acquire () is changed to Lock or Lock* acquire() then dmd will emit
'cannot implicitly convert expression (this) of type Mutexed to Mutexed*
'. To fix error 'this' argument should be taken by pointer, so it is ice on
accepts-invalid.
