Well rand() gives a different answer each time, so that can automatically be 
counted as being reassigned in the eyes of the infinite-loop-catcher.  If 
you try to implement your own RNG in a macro then obviously the random 
variable will be reassigned so that would also count.

Agreed.  Although I still think you could detect some common infinite loop 
situations without breaking any existing behaviour.
