Type inference issue when using Scala IO 0.4 Follow

Hi,

I've found a frustrating type inference issue when writing code which
uses Jesse Eichar's Scala IO library.

Here's a really short example:


import scalax.file.ramfs.RamFileSystem

object Test extends App {

    val fs = new RamFileSystem()

    val root = fs.root / "somedir" createDirectory()

    val indexDir = root / "_index" createDirectory()

    println("IndexDir =" + indexDir)
}



This code compiles OK but the presentation compiler complains about the
second call to createDirectory.

It seems to have inferred the type of root to be Any when it should be
at least Path according to the signature of createDirectory.

This of course means that any subsequent code won't type check unless
explicit types and casts are used.

This was using the latest IDEA EAP (117.281) and originally against
Scala Plugin build 683.  I also upgraded to build 708 but the same happened.

The project uses Scala 2.9.1 with the 0.4 release of scala-io-core and
scala-io-file for Scala 2.9.1 from Maven Central.

Interestingly I was previously using a SNAPSHOT build of Scala IO and
the problem didn't occur then.  I'm afraid I don't have and can no
longer find the source of the snapshot to see what changed between the
two versions.

So I guess this should be logged as a bug or is it an already known problem?


Thanks,
Steve Sowerby.
