@vach Would you mind elaborating on your asSequeence() comment? Or sending a link?

[vach]

sure so when i started with kotlin, i was using things extension methods on collections thinking that they actually use sequences or (java streams if i'm on 8)

[vach]

so writing list.map().filter().... i was really intending to do list.asSequence().map().filter()...

[vach]

this was the first time i saw performance degradation, and at first i thought yeah kotlin is slow, but really its me messing up and not reading the docs... (plus an issue that still exists my idea wont show docs of kotlin code)

[vach]

so basically list.map() will create a new collection
then the next operator will create another after that.. wile if you use asSequence or even better java streams you might do much better...
