I found this question and accepted answer on StackOverflow. It's related to the slow JSON parser in the standard Scala library.
The consensus as it were, is that the build-in JSON library is slow, and, in the words of DMC: "it's like that, and that's the way it is"
Maybe I'm just being naive here, but that sounds like a bad approach to grow the language. Shouldn't the built-in libraries be perfect? They don't have to be everything for everyone, and I accept that Scala is extendable. But, if there is a built-in library, then surely it should be rock solid and as fast as the language have to offer.
I'm lodging a complaint with Star Command ;-)
Does anyone know where or how a normal guy like me can voice my opinion on this, i.e. where we can go to help shape the Scala language?
Update:
This question was not intended in any negative way. Scala, it's creators and the Scala community is choc-full off goodness. I was simply surprised to see that something like the built-in JSON parser was far from optimal (according to the question in the link provided)
