--- Comment #1 from Jonathan M Davis <issues.dlang@jmdavisProg.com> ---
r.cache.writeln

fails on its own. This looks like it's a problem specifically with cache and not joiner, though it's not clear to me exactly what's going wrong. It looks like it's complaining that caches[0] and caches[1] are assigned values in one branch of the constructor and not another, but I have no idea why that would be an error. I've never seen anything like that before.

reduced example:

```
import std.algorithm;

void main()
{
    [1].map!(x=>[x].map!(y=>y)).cache;
}
```
