Sometimes you just want to call the copy method for the same "parameters", but not care about what underlying type it is.Because case class .copy() methods are auto generated per case class, you can't call copy on the abstract class, so this approach uses some scala foo to generate a scala Function that generates the correct magic for you.

Scaladays 2014 slides

As compiled by Kevin Wright a.k.a @thecoda

(executive producer of the movie, and I didn't even know it... clever huh?)

please, please, please - If you know of any slides/code/whatever not on here, then ping me on twitter or comment this Gist!

This gist will be updated as and when I find new information. So it's probably best not to fork it, or you'll miss the updates!
