I love redefinitions, but I don't think invoking the "spirit of Scheme"
regarding `set!' is useful, especially in the light of Steele and
Sussman's remarks in "The First Report on Scheme Revisited",
http://cs.au.dk/~hosc/local/HOSC-11-4-pp399-404.pdf:

    In retrospect, we can also see that some aspects of the initial
    design of Scheme were flat-out wrong ... [We] believe that Carl
    Hewitt was right: we would have been better off to have introduced
    cells as a separate, primitive kind of object, rather than allowing
    assignment to any and every λ-bound variable.

Regards,

Andy
