 and there is something worst : imagine that I want to introduce a back-door
 in plruby, I just need to run it with $SAFE = 8.

 Then I can say that plruby is safe because it run with twice the value of
 the original $SAFE (4), but I've the possibility to run code with another
 value. 

 This just to say that I *VOLONTARY* distribute *ONLY* the source of
 plruby, because I *REALLY* expect that someone else re-read it to find
 the problems that it can exist.
