Claire, attached is a new .ml version that has some additional code
to check on some special cases (since the original one you gave me
doesn't work with these cases). I feel it might be incorrect or
might have side effects. Could you look at it and let me know if it's
OK ?
thanks

I made some progress with this using different kind of Visitors. The
attached ml seems to do what I want (i.e., putting a s1: printf
"hello" at the outter most if and a s2: printf "world" at the inner
most if).I still feel it might have some side effects and
incorrect though --
