3 things I don't like about Scala: 1. It's based on the Java platform. 2. It's excessive use of operator overloading. 3. Mad implicit conversions all over the place. (yes, I exaggrated a bit ;))

'+' is just a symbol, meaning a lot of different things even in mathematics. All meaning is a product of convention. 3. In modern Scala, implicit _conversions_ are discouraged unless you know what are you doing. Besides, Scala IDEs are…

True story, I can infer what a '+' between two strings means, but what about all the non-intuitive operators? (List concats etc. pp.) 3. Not a big fan of IDEs. More of an editor dev, but good to know ICs are now discuraged. I got myself "Programming in Scala" back in the days and it se…
