You were 'forced' to start working on Git as a result of Jeremy Allison's reverse engineering of the BitKeeper protocol and Larry McVoy's hostile reaction.
At first you weren't too enchanted about the waste of time having to write your own DVSC system from scratch for lack of acceptable alternatives. I remember you complaining about that work preventing you to progress on the kernel.
Now Git is becoming the de-facto tool for source control management in most F/OSS communities and inside companies. That's another very successful project you fathered, and while I guess Mercurial or other projects would have existed anyway, the usage of Git on the kernel has demonstrated its reliability and its performance and traction have made DVCS'es gain visibility and market in no time.
Here come the questions:
* Are there any features you still miss from BK?
* As a happy Git user, I thank Jeremy Allison for his refusal to accept compromise and his tentative to create a Free BK client and I thank you for your refusal to accept a technically inferior/ill-suited solution like SVN. How do you reflect on this?
A branch of the Scala IDE for eclipse shows when there's an implicit conversion by underlining the converted expression. I guess this feature will come to other editors soon enough. Also, to have this conversion, you must have imported it (or its package object). The predefined conversions in scala.Predef are doing what you'd expect them to do and aren't very dangerous (much less, than say, built-in automatic conversion in some dynamic languages).
Implicit parameters are just like dynamic default values. Not a big deal really, especially since Scaladoc hides them by default, you don't even have to know they're here. But they open for a world of possibilities to change the behavior of an API.
In general, implicits in Scala are really a powerful tool and they're useful for API designers more than 'common' users. You said it's not about FP, but Scalaz which is the FP lib for Scala uses them to their fullest extent to replace class inheritance (considered harmful) altogether.
Your pejorative, and erroneous use of the word "socialism" betrays your bias.
All of these alternate languages can use the wealth of libraries available for Java, generally on all platforms on which the JVM runs. For example, I know of Scala apps that can run on Andriod, which is close enough to Sun's VM.
If you're not careful, you're going to catch something.
