The C<@ISA> array contains a list of that class's parent classes, if any. This array is examined when Perl does method resolution, which we will cover later. -It is possible to manually set C<@ISA>, and you may see this in older -Perl code. Much older code also uses the L<base> pragma. For new code, -we recommend that you use the L<parent> pragma to declare your parents. -This pragma will take care of setting C<@ISA>. +Calling methods from a package means it must be loaded, of course, so +you will often want to load a module and add it to C<@ISA> at the same +time. You can do so in a single step using the L<parent> pragma. +(In older code you may encounter the L<base> pragma, which is nowadays +discouraged except when you have to work with the equally discouraged +L<fields> pragma.)
