I'm sorry that you didn't understand me. I also think that having 
numbers behind the names isn't necessary at all and maybe even 
misleading, so I also would suggest to use symbols.

But if you read the original message, Garance wanted to be able to build 
sets of his constants and combine the sets with an "or" operator. For 
this I suggested use sets (of symbols).
