Which shows all the problems raised by Walter:
1. you need an entry in the dictionary that you need to look up 
for each new word that someone has introduced,
2. with natural language, you don't need to know its *exact* 
semantics when you use a new word, while in programming it is 
mandatory,
3. you *don't* want your programming language to arbitrarily 
change over time. That's probably the biggest issue.
