code compiles under scala 2.11.4 but not 2.11.5

[Jim Newsham]

I had some code which compiled fine with scala 2.11.4 and then fails to compile under scala 2.11.5.  I distilled the problem down to a fairly simple example and posted it at https://groups.google.com/forum/#!topic/scalaquery/LrHthnKqGZY since the code was slick-related.  They suggested it might be a compiler regression and suggested I ask here.  Any comments?

Thanks,

Jim
