Re: !0 is not necessarily 1 (was Re: Secret Perl Operators: the boolean list squash operator, x!!)

At this point, it's used as much as documentated features. Larry and the developers wouldn't change the value of true without taking that into consideration. They'd need an aweful good reason to change it. In addition, isn't there a mantra to the effect of "Perl is what perl does"?

In addition, isn't there a mantra to the effect of "Perl is what perl does"? If so, it's a bad mantra. People can't ever legitimately claim to know how to program in Perl if the definition of Perl changes with each daily build. If Larry replaces perl.c with hello.c, does "Hello, World" become the new Perl? ;-)	[reply]
