Hi, I’m trying:  
ruby 1.9.0 (2007-08-30 patchlevel 0) [i486-linux]  
in Ubuntu.

I’ve realized that there is no method String#any?  
Why? maybe it exists in a more recent version of 1.9?  
Which would be the replacement method if not?

Thanks.

Ok I’ve found that in Ruby 1.9 String is no more an Enumerable (and  
“any?” is  
defined in Enumerable module).

Right, so you just need to be specific about what you want to enumerate  
over:
