Sorry. :) I didn't mean that to sound insulting. I think the Java
culture takes privacy way too far, but I do understand that there are

Interesting. When do you use methods with the same names as instance
variables? The only time I can think of is when I want to do some sort
of lazy initialization thing, but then I think that the code
communicates better if I call the variable something like
"cachedWobulator" instead of just "wobulator".
I like the idea that an object is just something that responds to
messages; it bothers me, at some weird aesthetic level, that accessing
instance variables is different. At a more practical level, it bothers
me that I should have to think about whether to use "accessor methods"
or not. And at a completely superficial level, it really bugs me to see
the word "self" spewed all over my code. ;)
