I don't get you, this can be easily avoid with a strong naming 
convention. I mean, despite they are not really constants, you can still 
use variables to name your numbers and string, to give the reader a 
usefull hint on the meaning of your code. Yet it is still a matter of 
discipline, it is sometimes very tempting to put the string directly 
(unlike numbers string can be meaningful sometimes)
