In general seems like a good thing, just some performance / optimization things

To make this slightly faster we should just use a Set instead of an array

We shouldn't log the compiler result, that's a lot of info to pipe to stdout

... and stopping immediately on loops.
In order to support
passthrough, on loops we still return whatever the dependent file was, even though we "cannot use it". Anything else would make the term "passthrough" very strange for what we're doing there. But this might not be a sane default for other compilers which get stuck in self-reference loops.
