Scala 2.9.1 RC3

Hey guys,
Just a note that this RC will only undergo a 1 week RC cycle before potential release, so *please* notify us of your bugs ASAP.  If we get no blockers, then these same binaries will be your 2.9.1 and we can all rejoice at the improvements.

P.S.  Special thanks to Toni for continuing to make RC pushes *even on vacation*!!!

After a few additional refinements, a new release candidate of the

our Download Page at: http://www.scala-lang.org/downloads

This is a maintenance release: several bugs have been fixed, and
other improvements introduced. The new release is intended to be
fully binary compatible with the existing version 2.9.0.1.

Please help us testing this new release candidate, and let us know
of any issues you may detect, or of any binary incompatibility
issue that you may encounter. A description of the improvements in
Scala 2.9.1 is available below.


The Scala 2.9.1 distribution
==============================

This Release Candidate is made available for testing purposes only
and is not intended for production environments. We will wait at
least two weeks before issuing a final release, in order to
allow developers and testers to send us their feedback.


What is new?
============

The 2.9.1 release of Scala includes many bug fixes and
improvements, in particular to the interpreter: most of the
interpreter changes available in the development mainline have been
ported to the 2.9.x release branch.

In addition, the following changes (bug fixes and improvements)
have also been ported:

This looks like a blocker to me:

One of the bugs I have encountered earlier has resurfaced in 2.9.1 RC3
today.

If I use 'scala' for running scripts, it sometimes fails to find
packages on the classpath. This usually happens when mixing
compilation by scalac and scala and sometimes when compiling from two
different directories. Killing the FSC daemon (which is automatically
started by scala) makes it work fine again.

I haven't checked the bug DB, but I thought I will report it quickly,
in case it rings any bells with the developers.

I will try to make a reproducible test case, but I haven't pinned it
down yet.

https://issues.scala-lang.org/browse/SI-4395 for one thing.
