A similar test case:

<code>
class A:B{}
interface B:C{}
interface C:D{}
interface D{}
</code>

the following also fails to compile with circular inheritance error:
interface A{}
interface B:A{}
interface C:B{}
class Foo:C{}
int main() {
  Foo x = new Foo;
  return 0;
}
so it looks like changing the order of defining the interfaces doesn't fix
the issue.

Right. But I have it fixed anyway in .123, which I hope to post soon.

Cool, that's great to hear. :-)

Sorry to be a pest, but would it be possible to get more information in this kind of error message? At the moment, I just get this:

Error: circular inheritance of interface
--- errorlevel 1

Which doesn't tell me where I went wrong. It's okayish because I know where I've been working recently, but I'd like to double click on the error and have my IDE jump to my problem, or for it to tell me which interfaces caused the problems so I could hunt them down myself.

There are a few more errors I've encountered, which don't print file(line) formatted error messages.

That's getting better over time.
