Don't be so harsh to yourself! Nobody's perfect. I like your proposed 
change. It doesn't offer all the flexibility that has been talked 
about in the last couple of months, yet it is simple (as simple as it 
can get?) and doesn't change the feeling of the language.

I wonder how you'd design scoping rules for Ruby if you could start 
from scratch. Would it be like the proposed solution or something 
different?
