--- Defines reverse lookup table.

--- NOTE: Type intellisense simply does not work for this module, and there is no easy way to fix

--- # Example
---
--- ```lua
--- event.on_built_entity(function(e)
---   local player = game.get_player(e.player_index)
---   local controller_name = reverse_defines.controllers[player.controller_type]
--- end)
--- ```
