Suppose I want an array of value pairs, suppose for the sake of arguments, vertices, like X,Y (though, they don't have to be numeric types, I'm thinking generic pairs). I want to keep the list of vertices in a list.

What's the best way to store/organize them in perl?

It seems so wasteful to use an array of hashes (key/value) for a single pair, with key names like X and Y. 

%pair = ( X => 12, Y => 10);

#then keep in a list like this...
$pairlist[0] = \%pair;

And using the first (X) value as a key wouldn't work if you needed to repeat the value. 

%pair = (12 => 10);
# no list required, but then (12,10) and then (12,5) wouldn't work...

Of course, a simple array of arrays would work... 
@pair = (12,10);
#with a list assigned like...
$pairlist[0] = \@pair;

I guess I'm curious what y'all do?

I mean, besides making an object, which is a pain for something this simple, especially if I don't supplement my Perl with something like Moose, which I don't... (well maybe it's not a pain for you... but I'm pretty weak there...) ;)
