No. The editors are considering it & they want considered feedback  
from the community. I think compiler writers should talk about the  
real gains to be had from immutable pairs. We can take as given the  
answer from regular Scheme programmers.

Again, I don't want immutable pairs. I want disjoint 'list' & 'pair'.

I think Chicken will keep the 'bare bones' + 'optional meat'  
philosophy, come what may.
