I understand you, but reference counting help us to write a better
code, more object-oriented.

Simplicity. I think that's depends on point of view.
Today I write a better code than 3~4 years ago. For me it's much more simpler:
- no more .Free
- no more try-finally (to use .Free)
- no inheritance
- less variables and types declarations
- more functional design
I'm using decorator pattern. No problem with it, but delegates makes
me write less code and the design is awesome. None language has the
same feature, as far as I know. We have it, but doesn't work... well,
doesn't work in all cases, in all possibilities.
For me, it's a bug. Sorry.
