[Zope] The word "students"

Is the word "students" a reserved word in Zope? Apparently, I named a list "students" and then tried to populate it with the result set of a query. This variable was never populated and Zope did not generate an error. Also, I tested my query independently through phpMyAdmin and the Z SQL interface and it passed. When I changed the name of this variable from "students" to "studentNames", everything worked. Also, this is the only variable named "students" in my application. Your input would be appreciated. Thanks. - Asad
