That won't stop other people.

That isn't really all that useful. That line of code's only 
purpose is to be misused and cause misunderstanding.

Someone might come around and say, why modify documentation and 
code? Why not just modify documentation and then have the code 
read from that documentation and change behavior instead. That 
way you keep documentation and implementation in sync!

Kind of odd you have a 1:1 mapping for a scripting language 
anyways. That doesn't seem like a very rare occurrence. You don't 
pass any extra meta data for your implementations? They all have 
1:1 mapping for types? You implement things like pointers in your 
scripting language?
