Every thing is an Object. Names for things are not Objects because then 
it would not be clear whether you are doing something with the name 
itself or with the Object it refers to. My variable.rb code lets you 
refer to the names themselves instead of their value with the 
Variable[:x] syntax.

Perl and PHP IIRC do this with the \$foo syntax (and C# AFAIK uses the 
'ref' keyword for this, but don't quote me on this), but I think we 
should not have something like that in Ruby.
