Hi,

Do the changes to trunk also get applied to the 2.7.2 branch?

In particular, the fix for ticket #1335 (Stream.flatMap calls function twice
per element) doesn't seem to have been fixed in RC4.

The reason why I think it didn't reach the RC4 branch is that
List.projection still doesn't work for me. See the relevant thread here:
http://article.gmane.org/gmane.comp.lang.scala.user/8767

regards,
Harshad
