now i've looked and looked and i still don't FULLY understand how to declare a variable globally (all the different ways)

I know that i can use strict and declare variables globally using 'our'.. ie: 
use strict;
our $var = 22; #global var (or so i think)

[download]
and i have this vague notion that a variable can be global if i do this: 
$global::variable = 'global'; #global variable
print $global::variable; #but it looks ugly

[download]
so here's my question. Is there a way to let a variable be a variable (just $variable) without the use of 'our' and still have a clean program without warnings? Just curious, and a bit confused. I couldn't find a full explanation anywhere on perlmonks and i did do a whole lot of searches.
