      Give your opinion for the inclusion of new #scala collection operations http://bit.ly/2wVIMIy  (https://goo.gl/forms/TWcrH81MoRppvXwN2 …)

      Instead of fixing the performance issues with collections, #Scala decides to just add new methods combining multiple existing ones? Sad.

      It's a form delegating that decision to *you*. If you really think performance and new ops are mutually exclusive, say "no" to them all!

      It's also basically impossible to, say, write "intersperse" efficiently by combining other ops. It would be welcome in the new collections.

      Core problem is that collection operations cannot be efficiently combined. Adding more operations is addressing the symptom, not the issue.

      I think it's orthogonal. With my example of intersperse, it's hard to write the function expressively in source from existing operations.

      And yet it's a common operation which I find myself writing many times a year.

      This approach is maybe useful for proving your own argument, but some people (like me) actually want to engage and hear objective criticism.

      Because I actually believe you still have valuable contributions to make, and that people *ought* to listen, if you were more constructive.

          I'm not saying anything that shouldn't be glaringly obvious to anyone who has used #Scala, and it's not like I didn't say it before either.
