GenericIOError printing

[Stepan Koltsov]

Hi.

Code:

```
import io.errors.*;
import printer.*;

main() {
    println(GenericIOError(2));
}
```

prints, as expected:

```
error(2): No such file or directory
```

But code

```
import printer.*;
import io.errors.*;

main() {
    println(GenericIOError(2));
}
```

prints

```
GenericIOError(2)
```

Is is possible to change library code some way to make sure that GenericOError is always printed with error message despite of import order?

At a glance, since io.errors loads printer, the user-level import
order shouldn't matter since the dependency graph should be the same
in either case. Maybe there's an import circularity between io and
printer? Finding and breaking that circularity should fix the problem.

Yes, it was cyclic dependency.
