I vote yes on the first one.  For the second one, I'd like to review the 
affected primitives, but it sounds reasonable.

I vote no.  Although I'm in favor of making Scheme more functional, I'd 
want to see a change like this as part of a larger proposal that deals 
with such issues.  Just as an example, I'd be more interested in the 
addition of a more general immutable tuple type.

I vote yes to making it valid.  I don't currently have an opinion on how 
to do it.
