...was being assigned to like so.

string ret = thing.getString();

Apparently that does not work...

...Cmd ret;
		TMemoryBuffer trans = new TMemoryBuffer(data);
		auto prot = new TCompactProtocol!TMemoryBuffer(trans);
		ret.read...

Loosely-related, compiling

...
auto ret = arr.filter!(myFilter());
...

I got:

Error: closures are not yet...

...maximum() const {
	auto ret = this;
			
	while (ret.right_) {
	    ret = ret.right_;
	}
			
	return ret;
    }
}
```

It failed...

Before the call to leave, which puts...

try and see ;) Actually it may be...
