A modern programming language that makes developers happier.

So, tell me if I'm wrong. AFAIK, *`inline` sacrifices the size of the binary in favor of fewer stack frames and faster execution.* Is that correct? Is it more subtle or complex? Is there anything else it does that I should know?

Nobody cares about the number of stack frames because JIT optimizes it on its own

More other, inlining things may break some JIT optimizations and slow down the execution

`inline` in Kotlin allows:
1) to skip creating objects when using lambdas
2) to reduce method count for trivial methods
3) to get richer control flow

I see... How can I tell if I shouldn't be `inline`ing something?

The simple answer it to never `inline` unless you know what you are doing

A more complete advice is to respect IJ when it tells you that something shouldn't be inlined

Actually I am surprised it is NOT in the docs <https://kotlinlang.org/docs/reference/inline-functions.html>
