Ch2:Step5 pre-post increment operators

Posted: Jun 6, 2008 2:03 PM

"Note that Java's ++i and i++ don't work in Scala."

Why? It'd be nice to see a footnote describing whether this was because of a limitation of the language or language syntax decision.

It seems from what I've read from Chapter 1, Scala is expressive enough to make such an "operator overloading" (wrong term, I know) possible.

The statement quoted above is begging for more detail! :)

I think that Scala is trying to promote programming with immutable objects, while increment operators are clearly intended to be used in with mutable variables in constructs like (C#)
for (int i = 0; i < 5; i++)
- which would be a bad style for a functional Scala language.
