Using Glib::Object::Introspection to have access to Gtk3

[Anirvan Sarkar <powers anirvan gmail com>]

I am trying to port a Gtk2-perl application to Gtk3. I came to know about the Glib::Object::Introspection module. Its synopsis at https://metacpan.org/pod/Glib::Object::Introspection says that one can do:

use Glib::Object::Introspection;
Glib::Object::Introspection->setup(basename => 'Gtk', version => '3.0', package => 'Gtk3'); 

to have access to Gtk3 library. So does this mean that it we can replace

use Gtk2;

with this without any problems (except use proper Gtk3 syntax wherever required)?
