Single abstract methods and closures
Mon, 2011-11-14, 13:58
Dear Scala users,
I remember there was talk about allowing to supply closures where a class with a single abstract method (SAM) was expected (cf. http://www.scala-lang.org/node/8744).Are there any news from this feature? Any plans to integrate it in the upcoming versions?
Regards,
Gilles.

Re: Single abstract methods and closures
For proposed Java8-compat or are there other reasons?

1) you can get rid of a lot of implicits
2) there are some performance advantages to SAMs

how can the compiler avoid wrapping the sam into a function when more than one sam is used?
