I need confirmation of something not documented anywhere:
```myMutableMap.values.removeAll { &lt;predicate&gt; }```
Will this remove entries from the map?

Yep. Kotlin mutableMapOf is backed by java.util.LinkedHashMap. LinkedHashMap.values() documentation says: `Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa.`

... so it really depends on your predicate: for `.removeAll { false }`, the answer to your question is no. :smile:

So it depends on the map implementation, that's why it isn't documented in MutableMap
