I'm very happy that you are taking an interest in Calc again, and especially 
that you took the trouble of digging into the ramifications of this little 
correction! I'm most curious to hear what you found out. You see, when the 
change to calcFunc-gcd was made, naturally I did look at its callers carefully 
to assess the impact. Now since you brought it up I've done so again, and found 
nothing new: all users of that function are either indifferent to the change, 
or actively benefit from it.

It seems clear that the code is less buggy now than before the change and 
should therefore be preferred for the sake of correctness. However, I could be 
wrong, and would very much benefit from your findings so that my mistakes can 
be fixed on master!
