I wanted to create pretty urls but I couldn't do it in a simple way because the developers thought that in a path can not be optional parts, like: /article/1/article-slug and /article/1

So they removed a useful feature. And it was in a 2.x -> 2.x+1 release... Yesterday it worked, today not. I was not happy. :)

My othern concern with scala, what is mentioned in the article, is the operator usage.

How am I supposed to "invent" this <:< notation for adding headers? (dispatch lib) `val svc = url(object_url) <:< Map("User-Agent" -> "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)")` or in squeryl, converting a boolean into a "query boolean": ``` val fls = false fls.~.? ```

Other than these, I like it. When I am coding in JS or PHP I always praise the scala types/ compile time checks. I am almost afraid of dynamic typing since I tried scala. :)
