any notable difference between removeIf((E) -> Boolean) and removeAll((E)->Boolean)?

[Leon Linhart]

removeIf is not part of the stdlib but of Java's collections since Java 8. I'd just use removeAll since it's MPP compatible but if you only use Kotlin with Java >= 8, it does not really matter.

I also prefer the later syntax-wise

Note that since removeIf is not an extension function it can do some performance optimizations (e.g. moving elements around in one go for ArrayList), which removeAll cannot do. In certain situations that might be desirable instead.
