-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the

-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.

+    * `power` Increase percentage
+    * `punch` Multiplier
+    * `infinity` If `1` then it is infinity enchanted
+* `get_string(key)`: Returns `""` if key not present. See below fields for all enchantments:

 ---@field handle_node_drops fun(pos: Vector, drops: string[], digger: ObjectRef) `drops`: list of itemstrings. Handles drops from nodes after digging: Default action is to put them into digger's inventory. Can be overridden to get different functionality (e.g. dropping items on ground)
+---@field register_on_dieplayer fun(func: fun(player: ObjectRef, reason?: string)): nil Called when a player dies. `reason`: a PlayerHPChangeReason table, see register_on_player_hpchange
+---@field register_on_player_hpchange fun(func: fun(player, hp_change, reason), modifier): number Called when the player gets damaged or healed. `player`: ObjectRef of the player. `hp_change`: the amount of change. Negative when it is damage.. `reason`: a PlayerHPChangeReason table.. The `type` field will have one of the following values: `set_hp`: A mod or the engine called `set_hp` without giving a type - use this for custom damage types.. `punch`: Was punched. `reason.object` will hold the puncher, or nil if none. `fall`, `node_damage`: `damage_per_second` from a neighbouring node. `reason.node` will hold the node name or nil. `drown` `respawn`. Any of the above types may have additional fields from mods. `reason.from` will be `mod` or `engine`. `modifier`: when true, the function should return the actual `hp_change`. Note: modifiers only get a temporary `hp_change` that can be modified by later modifiers. Modifiers can return true as a second argument to stop the execution of further functions. Non-modifiers receive the final HP change calculated by the modifiers.
