I have a question about how ruby-like is it to capitalize
instance variables. Often I think of the first character
of an instance variable to be the first character following
the '@' sign. 

So, with this thinking, I am NOT inclined to use @Foo, 
because I tend to think of it as a member form
of Foo, which is a constant. So, although @Foo is perfectly
legal, I don't see it used much.

Is there a good reason that I should avoid using capitalized
instance variable names?
