and it does complain if I do something like tailrec suspend fun factorial(n) = if(n == 1) { 1 } else { n * factorial(n - 1) }

Is that tailrec? It does something with the function return.

[Bob Glamm]

the ^^ factorial function above is not tailrec for exactly that reason as far as I'm aware

[Bob Glamm]

the function I traced was tailrec for sure: just tailrec suspend fun foo(n) = if (n == 1) { 1 } else { foo(n-1) }

[Bob Glamm]

then foo(700000) and watched the stack trace of the thread in IJ debugger with a breakpoint on `foo(n-1)`; stack depth stayed constant
