Eh? You can just use public static variables, can't you?
In fact, in an OO perl program with "use strict" you'd
probably lump your globals into a package:
package Foo::Global;
use vars qw($frob @wibble);
$frob = 23;
@wibble = (1..10);
and in Java you'd do the same thing:
package Foo;
public class Global {
public static int frob = 23;
public static int[] wibble = new int[] {1,2,3,4,5,6,7,8,9,10};
}
(Not directly related to the above:
Perl's tremendous fun, I agree; but it doesn't follow that all
other languages are "crap" :-) )
(Unprovable opinion:
We can all sense that Perl's use in commercial environments
has peaked, hence the sudden outbreak of defensive "advocacy")
