you've either fetched a really old gtk2-perl (<0.20) or you've found  
buggy examples.  where was the example code?

Gtk2->init this is the perl version of gtk_init().  it is bound as a  
class static method for Gtk2, since it modifies the internal state of  
the gtk+ library.[1]  the perl wrapper is smart enough to find and  
modify @ARGV for itself, so you pass no arguments to it.

reference docs for gtk_init()
   http://developer.gnome.org/doc/API/2.0/gtk/gtk-General.html#gtk-init

reference docs for Gtk2->init
    
http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/ 
main.html#boolean_Gtk2_init

since 95% of the time you want Gtk2 initialized in your main program,  
Gtk2 offers an import argument, "-init", which calls Gtk2->init for you.

  use Gtk2 -init;

is equivalent to

  use Gtk2;
  Gtk2->init;



[1] or because it's "object-oriented", in the buzzword-sense of the  
term.  see the methods versus functions thread for more philosophy on  
that.
