It might be possible in code because it's more constrained enviroment but well it hasn't been solved in general typesetting. The rules are very hard to hardcode because it is subjective and often requires broad context (like understanding line above or what you do with names). Thats why it has been always done by humans if you want good results. And its not like smart people havent tried (like Knuth for example).
