 User Changes:
 
 * Added `arrayFindAny` and `arrayFindFirst` functions to expressions. As the name suggests, those functions will try to find an element of an array or return `null` if the array is empty.
+* Added `chain` function to expressions. This function operates on the results of the first one and allows chaining multiple function calls together like so:
+  ```
+  //`it` is the result of the previous function, unless there's a lower level lamda.
+  chain(arrayOf(2, 3, 6), arrayMap(it, sqrt(it)), arrayFindFirst(it));
+  //this is the same as:
+  arrayFindFirst(arrayMap(arrayOf(2, 3, 6), sqrt(it)))
+  ```
 * Java `Iterable`s can now be converted to arrays.
 * Added `remove` to `cmd:data`.
 * Added `cmd:operate` to the `scoreboard players` command.
 * Added registry access for expressions! Now you can access the game's static and dynamic content registries by using new `Registry` and `DynamicRegistry` functions.
   * Why is this useful? For example, this allows you to compare item stacks based on their item type:
   ```
-  this_entity.getHandItems[0].getItem == Registry('item').chest
+  this_entity.getHandSlots[0].getItem == Registry('item').chest
   ```
   * For item and block registries there is a shortcut: `Item`, `Block`.
   ```
-  this_entity.getHandItems[0].getItem == Item('chest')
+  this_entity.getHandSlots[0].getItem == Item('chest')
   ```
   * `Biome` and `DimensionType` are available dynamic registry shortcuts.
