      Have you ever wanted to define a default for a type parameter in Scala? Here's how:https://gist.github.com/propensive/8894fd2a58ac93bfa2c3 …

      @tpolecat @propensive not obviously ethical either if you ask me ;) I'm curious of the use case?

      @aloiscochard @tpolecat @propensive could be useful to do something similar to the way we use NotNothing: https://github.com/scalaz/scalaz/blob/series/7.2.x/core/src/main/scala/scalaz/NotNothing.scala …

      @puffnfresh @tpolecat @propensive I'm not so keen into adding features that support exclusively hack :-p

      @aloiscochard @puffnfresh @tpolecat How is it a hack? It's designed to do that! The motivating use case was the collections library...

      @propensive @puffnfresh @tpolecat more seriously, those kind of feature should be supported natively imo, I know I'm dreaming though ;)

      @aloiscochard @puffnfresh @tpolecat I think there are plans for something "cleaner" in the medium/long term. Can't say more than that.
