Here's a simplified snippet:

add_item(Player=#{ inventory => #{ ItemID => # { quantity = Q }}}, 
ItemID, ItemInfos) ->
     Player#{ inventory => #{ ItemID => #{ quantity => Q + 1 }}};
add_item(Player, ItemID, ItemInfos) ->
     Player#{ inventory => #{ ItemID => ItemInfos }}.

Pretty clear what this code is doing, the equivalent with functions 
leaves me scratching my head. This kind of syntax also allows you to get 
it right the first time a lot more often than with functions.

I need to do things like this for more than 500 different actions. 
There's not enough time in the world to do it with functions. That 
particular project is on hold until I can avoid wasting my time btw.
