Stacks for Kotlin: Design Notes and Local Lifetimes for Kotlin: Design Notes
Then Stacks build on it to make
local parameters let the compiler prove a value won't escape a call. That single primitive unlocks: non-local return without inline, stack-allocated vararg, view types that can't outlive their source, builders that statically prevent receiver leaks.Then Stacks build on it to make
suspend just one of many possible suspension mechanisms. Each coroutine-like API (`Sequence`, Flow, deeply-recursive) gets its own typed continuation instead of fighting over the single global one. @RestrictsSuspension becomes obsolete. KT-3480 fixes itself. DeepRecursiveFunction shrinks 9×.GitHub
