Why no i++ in Scala?

Question

I just wonder why there is no i++ to increase a number. As what I know, languages like Ruby or Python doesn\'t support it because they are dynamically typed. So

Answer 1

Quite a few languages do not support the ++ notation, such as Lua. In languages in which it is supported, it is frequently a source of confusion and bugs, so it's quality as a language feature is dubious, and compared to the alternative of i += 1 or even just i = i + 1, the saving of such minor characters is fairly pointless.

This is not at all relevant to the type system of the language. While it's true that most static type languages do offer and most dynamic types don't, that's a correlation and definitely not a cause.
