Scala emoticons

There are a lot of great things about Scala, but there are a few things where that programming language just goes overboard. Consider that there are several emoticons built into the standard library:

  • +:= (vampire pope) for adding items at the front of a sequence
  • <:< (sad witch) for comparing generic types
  • :/ (uneasy) fold right

And that’s just the ones I know about. Unfortunately, you can’t use a search engine to find any more, because none of the major search engines index emoticons. :/ (try it). Fortunately there is a well-hidden reference page.

Post a comment if you find any more.
