Господи! Это каких же глюков можно наловить!
PS: Там еще в конце забавно: The weaken and isweak subroutines in this module and the patch to the core Perl were written in connection with the APress book ‘Tuomas J. Lukka’s Definitive Guide to Object-Oriented Programming in Perl’, to avoid explaining why certain things would have to be done in cumbersome ways.
