As a fan of Scala and a developer who has been distancing himself from anything C-like for a decade, I found this post to be pretty fair. Go seems to force explicitness; Scala can be explicit or implicit depending on who uses it. In general, I find explicit to be preferential to implicit when I'm trying to learn a code base. BUT, some cases I hate handling explicitly, such as NULL. For those cases, you can limit the need to handle them using Scala.
