I have questions on Kotlin Features Survey
1-Static members in Kotlin classes #17 why people doesn't want it?
2-Optional (trailing) commas #11 what is this feature?
3-Collection comprehensions #7 what is this feature?

amorenew: 1) For me, object fills the same role. I wouldn’t really want both (although I didn’t participate in the survey). If someone wants static for jvm interop there’s @JvmStatic 2) Trailing commas in lists would be legal, ie. listOf(1, 2, 3,) would compile, currently it doesn’t, mostly I think this is useful during code generation. There’s also another feature that’s alluded to, but I’m not sure what that was. 3) https://en.wikipedia.org/wiki/List_comprehension another syntax for loops.

amorenew: ad. 2 you can e.g. have constructor parameters, each in new line, and last one would have a comma after it as well. I’d like it because you can then rearrange things without having to add/remove comma if you move the last element, and you see 1 line changed in VCS if you add an element to such list

constructor( arg1: Int
, arg2: Int
, arg3: Int
) {

or rearrenge using idea change signature refactor

@msink this moves the problem to moving the first element, still 😉

[wasyl]

and @agomez just using move line is way faster than any refactoring. The feature is there in Groovy, and I really like it for my Gradle scripts

[agomez]

yes, but if you invoke it from somewhere not using named params you'll break your code

Lucas, well moving the line does not search for usages. So you migh as well use the "move argument" function in IntelliJ. Try it: `ctrl`+`alt`+`shift`+`→`
