I look at bind as the difference between by reference and by value semantics.
When using scope delegates (or delegates that could be scope delegates), this
difference rarely matters. When passing data between threads, the need to pass
by value becomes more important. "By value" may even require a deep copy.
Even though I can see uses for some kind of bind functionality in D2, I need to
see where all this "shared" object stuff goes before I know what/if a D2 bind
library should do.
