I asked this because it doesn't even feel like *the const system* is 
finished (ready for practical, large-scale usage), in a worthwhile 
sense. For example, without a mechanism like the 
equivariant-functions/scoped-const/romaybe or something similar, there 
are lot of cases where using const correctly will be tedious and annoying.
And if that is the case for the const system, how about concurrency and 
all such features that aren't even released yet?.. The book and it's 
deadline is your responsibility of course, and in any case I wish things 
get finished on time, but if they don't, I just hope that that won't 
adversely affect D's development itself.
