As you have pointed out, either way is a double-edged sword; one programmers rigid and inflexible code is another programmers safe and reliable code, and all engineering is compromise.  That being said, in my experiences, the only proven way to know when the customer is going to change the requirements is when he says they are never going to change the requirements.  For something like a game, assuming a fixed number (especially one) of anything is a surefire way to incur massive rework.  Suppose, for instance, the game evolves to a multiplayer version; a server might need to host a dynamic and always changing number of game engines.

I guess generally I mean "referentially transparent", but more practically I mean "pragma Pure".
