Hi, I don't fully understand what option a) implies. If an user receives a
warning, can (s)he continues working?. And what next?. Will (s)he get an
error sometimes?. In my opinion if there is a risk of conflict bettwen a
command or funtion name and the name of a field or variable this name
should be prohibited. So, i think the most restrictive option should be
implemented (whith a very clear message saying "the word XXXXX is a
reserved word, choose another for your variable name").

Saludos, Pedro
