I will presume you are merely joking, but for the benefit of any beginning programmers reading this, the closure above is a standard functional idiom for partial evaluation of a function (in this this, re.search(crex,txt)) | class Searcher(object): | def __init__(self, rex): | self.crex = re.compile(rex) | def __call__(self, txt): | return self.crex.search(txt) while this is, the equivalent OO version. Intermdiate Python programmers should know both. tjr -- http://mail.python.org/mailman/listinfo/python-list
