I can't find anywhere where that is quoted in context. Considering the amount of effort that has gone into making Perl do what is meant when the code is ambiguous I very much doubt if he meant what you mean. If he had thought it was a bad idea to call shift with an implicit parameter then I don't think he would have designed the language so that you could.
