Deprecate auto-tupling?

[Alex Cruise]

I was making Akka requests like this:

  someActor.ask(someMsg, 30000) 

and, since ask is defined to take an Any, the compiler helpfully auto-tupled me out of a type error and into a confusing ten minutes.  Can we get rid of this "feature"? :)

Did you try -Ywarn-adapted-args option?

Nope. Can we turn it on by default? :)

Hi Alex,

seriously, given previous experience (i.e. man hours wasted) I'd rather have -Ywarn-adapted-args on by default at error level. What makes you say that auto-tupling is a good idea? Or was that meant as sarcasm?

Good question. I don't have any idea how stable/reliable that option is.

Please file a ticket for and set fix version to 2.11-M3 so we can look into that when we have a little bit more time.

Looks like I haven't had to touch it in 19 months, and the test continues to pass. By the prevailing standards of stability you could found an empire on such bedrock.

Also, this has been in -Xlint for the whole 19 months. Six little characters.

Point taken, pom updated.  But still, is anyone going to argue *for* this "feature"? :)

In many ways argument lists and tuples are very similar concepts. However Scala is lacking a proper synergy between the two. I would argue that auto-tupling provides at least some way to bridge between them. So this is a very useful feature.

If you want an example on how auto-tupling can be used in real world, then have a look at the "Magnet Pattern": http://spray.io/blog/2012-12-13-the-magnet-pattern/
