Mine's at 9 without any real golfing. No newlines though. Maximum line 
length's 67, and that's the largest by far. I use "cond ? true : false" 
4 times though, and that could be cleaner, I imagine.

However: While it passes all the tests, it might have some poor flaws in 
real world use.

i.e:
   * Anything with the same hash would have the same attributes. (i.e: 2 
string objects containing the same text)
   * Every instance of the class that uses the attribute is kept in 
memory so long as the class is.
   * foo? returns the value, instead of exact true/false. While this is 
legit, it can't be used in (a.foo? == false) conditionals. But that's 
unrubylike anyway :D
