Well, good, because indeed it is not the solution to multi-threading. 
And it is not even *a* solution (as in, one of many solutions). The 
const system is first and foremost an improvement on the static type 
system. In addition, the const system, specially invariant (and upcoming 
features such as pure functions) also allow for _some *particular* 
optimizations related to concurrency_. But it's nowhere near a full 
solution like STM, message-passing, or other things in the same category.
I hope everyone acknowledges this (and from what I've in some other 
posts, it seems that's not the case). I know Walter has said that 
const/pure is "key to multi-threading", but I'm fairly sure it was meant 
in the sense that const/pure was necessary for a concurrency solution, 
but was not the whole solution. And it clearly is not.

(note, I'm not disparaging the const system because of this, I'm only 
clarifying its objective)
