I'm reading this: <https://android.jlelse.eu/inline-noinline-crossinline-what-do-they-mean-b13f48e113c2>

what's the behavior when I don't specify any of `inline`, `noinline`, `crossinline`?

Well, `inline` is different than the other two, since `inline` applies to functions, where as `noinline` and `crossinline` apply to _parameters_ of inline functions.
If your function is `inline` and you do not specify `noinline` or `crossinline` on a lambda parameter, then that lambda will be eliminated by inlining the function into the callsite.
