Thanks and sorry for the noise. I should have checked bugzilla first:

   http://d.puremagic.com/issues/show_bug.cgi?id=3051

   http://d.puremagic.com/issues/show_bug.cgi?id=3052

This one is opened by David Simcha when implementing std.parallelism:

Then I guess my examples used to work due to dmd bugs that must have 
gotten fixed during the short lambda syntax implementation.
