# Objective
This is a rebase of #3701 which is currently scheduled for 0.8 but is marked for adoption.
> Fixes https://github.com/bevyengine/bevy/discussions/3609
## Solution
> - add an `insert_boxed()` method on the `Map` trait
> - implement it for `HashMap` using a new `FromReflect` generic bound
> - add a `map_apply()` helper method to implement `Map::apply()`, that inserts new values instead of ignoring them
