Ari, warnings about deprecations are just that. Warnings. They ARE  
true. In the future these things will be removed and their  
replacements already exist. Sometimes they are just synonyms and  
sometimes they are actually different implementations. Any time you  
see such a warning just try to find the method that should be used  
instead ( ri is a good way to check this, there is usually some blurb  
telling you the alternative method.)
Generally, Matz is slow about completely removing that functionality  
to give time for people to change and refactor old code. But don't  
depend on it.
