Is there a way to avoid using to! conversion here?

immutable string[] dst = to!(immutable string[])(array(pipe.readEnd.byLineCopy));

Are you looking for something like assumeUnique [1]?

```
pipe.readEnd.byLineCopy.array.assumeUnique;
```

It's just a nice wrapper for cast(immutable string[]).

assumeUnique.

immutable string[] dst = pipe.readEnd.byLineCopy.array.assumeUnique;

Arguably, to!(immutable string[]) should work on the result of byLineCopy, but it doesn't seem to. If it did, then that would eliminate the need for assumeUnique, and it's always better to avoid assumeUnique if you can. However, given the current limitation with to and byLineCopy, it probably is the best solution.
