Not sure what to say to that, except that it might have been a long time ago, or with some very specific libraries or teams? If it was years ago, then I can say that things have changed a lot since the last time you touched Scala, and in the right direction. Most of the criticisms from, say, 5 years ago, are being addressed. For example, if by "operator overloading" you mean "symbolic method names", then those have largely fallen out of fashion. sbt has seen huge improvements (some people dislike it, some people like it, but it's one of the most powerful build tools out there). Compilation times also have improved. As far as I am concerned, it is my favorite language, and there is so much going for it: great tooling, the upcoming 3 version, binary compatibility improvements, rock-solid JavaScript compilation, native compilation under development, and, of course, all the benefits from a language with one of the most powerful types systems around.
