@Experimental Kotlin coroutines
summary
Kotlin coroutines are stable in 1.3 but several API bits remain experimental or obsolete and may change. The session shows concrete patterns: using Channel, Actor, Select to implement a hamburger-stand simulation with two cooks, a producer of orders and a massive run of 8 people × 3 requests (24 actions) yielding 9 final orders. It demonstrates buffering modes (rendezvous, conflated, buffered, unlimited), differences like produce vs actor builders (produce auto-closes, actor must be closed), and using select to pick the first ready resource.
