Regarding some of the "brainteasers" posted in the article, I am assuming that most of them are simply bugs that will get ironed out in version 2.9.2 or thereabouts ? eg. The following fails: Set(1,2,3).toIndexedSeq sortBy (-_) But doing the same in 2 steps, ie. after assignment, works val xs = Set(1,2,3).toIndexedSeq; xs sortBy (-_) I have been bitten by this several times now, so I don't unnecessarily chain > 2 functions even if it does compile ( which also solves one other brainteaser posed in that article ) Have also seen the problem with the add function, when I wrote a matrix manipulation library. def add(x: Int, y: Int) = x + y add(1,_) fails, but add(_,_) works. Even though the error message " missing parameter type for expanded function" seems reasonable, and providing the parameter type ie. add(1,_:Int), does compile, the bahavior is hard to explain to newbies. His point about hanging your hat on asInstanceOf[...] and the resulting code being clumsy...ok, guilty as charged, but then you only have so many hours in a day, and mgmt is paying $$ to solve boring business problems ( compute the asset quality of five million loans in thirty lines of business over twelve quarters using scala ) and not mucking around ( add a filterMap to the scala collection library to get an idiomatic Scala implementation ) I enjoyed the programming snippets in the article very much, but I still don't get what the point of the rant was. He goes on and on about "lack of acknowledgement of complexity", but what does that really mean ? Does he want like a gold star ? Even if everybody acknowledges that scala is complex, what then ? Eventually some of it will get fixed & the rest will not & life will go on. Why be a downer at such an early phase of growth of the language ? All this talk of excess complexity will simply scare off the early adopters. Java has been around for 15 years and we still don't have decent generics. Scala is so far ahead in such a short time. Patience, etc.
