Would you mind creating a more minimal test case? We don't want to have to build all of Scalaz7 just to create a test case for this.

Thanks!

Sorry, I am quite new to Scala (as in less than 1 month). I actually do not know what is going wrong here. This is as minimal as I could get, but I do not know the internals of Scalaz, hence I do not know how to make it simpler.

Compiling with scalac produces:

error: java.lang.IllegalArgumentException: transpose requires all collections have the same size

This is almost certainly a duplicate of #5683. It doesn't crash in 2.10.0 RCs. It still doesn't infer the the parameter.
