A modern programming language that makes developers happier.

There is the new inspection for combining multiple collection operations. In one case, it offers to combine `map` and `joinToString` which looks harmless but actually the lambda in `map` is inline while in `joinToString` it's not. Is this an issue? I understand that the extra lambda allocation is probably compensated by the saved `List` allocation but the code size and method count grows a little.

Good point. I'd say this inspection makes code faster, and almost always it's more important that tiny code growth. But in general case, you're right. Do you think we should not offer this change for `map` + `joinToString` combination?

Maybe add a note to the quickfix text "(Lambda will not be inlined anymore)"
