I have never heard anyone on the committee even hint that we should add all proposed features to the language. Different members of the committee have different complexity budgets, both in magnitude, but more importantly, in how we weight complexity: Kernel semantics? Overall user semantics? Implementation? Ease of use for novices that don't quite have any accurate semantic model? Ease of reasoning about programs, either informally, formally, or by automated tools? I think all of us would agree that all of these are important. But each of us would bring tremendously different weightings to these issues. However, since the committee works by consensus, not majority, hopefully the end result will more closely approximate the intersection of our various budgets than the union. > > On the concrete proposal I note that the strawman claims this can be > used to implement bignums, but it seems to me there is no way to > implement storage of arbitrary size so that would appear to be > impossible.
