Since it is not my own code ...
The problem is that little problems like this HAVE been duplicated and
no one has complained before ;)
Now we have to go through every library and eliminate them ...

Actually the proper way would be to get each function to produce a
single result - but I'm not going to re-code everything :)
I suppose the REAL questions was - "Why was using the function in this
way a 'bad practice', is there any way that it could be made a 'good
practice' since the intent is so obvious?"
I understand the new checks, but I don't see that the original was
particularly 'bad' - only that under some conditions it might cause a
problem?
