I beg to differ.
Maintaing source compatability where possible with new library versions
(without having to mess with clients) is an important aspect of interfaces.
Any language construct that fails in this regard (like with) is very bad
- period.
Again, our perspectives on what is important is different, as a library
maintainer, I see this as much more important an issue than you do.
