Interesting. As I get on Windows:

> y
('#<procedure cons> 1 2)
> (eval y e)
Unhandled exception during evaluation:
&who: generator
&message: "expecting a procedure"
&syntax:
  form: '#<procedure cons>
  subform: ('#<procedure cons> '1 '2)

See:
http://eval.ironscheme.net/?id=(define+e+(interaction-environment))%0A(define+y+(list+(list+'quote+'cons)+1+2))%0A(set-car!+(cdar+y)+cons)%0A(write+y)+%0A(eval+y+e)

Perhaps a bug on Mono?

Cheers

PS: Having that behavior will cost no more than a few lines of code, but I
am not sure something like that will ever be portable.
