no he didn't, -> is for REFs, and @ISA/bless is for OO	[reply]

`->` in general is for refs, but `->name` is for OOP. It even works on more than refs. JavaFan also forgot the universal base class `UNIVERSAL` and the methods is provides.	[reply] [d/l] [select]

yes, but I wasn't sure if UNIVERSAL may already have a meaning for classical packages, with the methods called with :: well I'm too tired to look it up now ... vote me down guys .. good night! Cheers Rolf	[reply]

nope! -> has a special meaning for OOP to call with an included extra parameter ... the packagename or the selfref. just try `->name` on a unblessed ref ... ...and log in again ;) perlop `Otherwise, the right side is a method name or a simple scalar variable containing either the method name or a subroutine reference, and the left side must be either an object (a blessed reference) or a class name (that is, a package name).` Cheers Rolf	[reply] [d/l]
