     "Allow" is not the same as "Require".  One of the things Steele
demonstrated with Scheme was that requiring support for higher order
functions could still allow generation of efficient code.  Mandating
proper tail recursion, on the other hand, is a requirement for
generating efficient code.  I think that part of previous scheme
reports was a great idea.
