Hi,
I am not trying to argue about your personal preferences, but allow me two
more questions:
1) what is the meaning of "result" in the case:
(print "Hello" 1)
, is it only the returned value 1?
2) What would you choose from the four choices:
a) the possibility to interchange 2 + 4 and (2 + 4)
b) the possibility to interchange (2 + 4) and 6
c) neither a) nor b)
d) both a) and b)
