Your "push" just pushes two simple values into @array. You're looking for this:

push @array, [$foo, $bar];

Here, the [...] construct defines an anonymous array containing $foo and $bar. The (single) value pushed into @array is a reference to this anonymous array.

Later you can do things like this to access the individual elements:

@barfoo = blah();
foreach my $bf (@barfoo) {
print $bf->[0], $bf->[1];
}
or
print $barfoo[0]->[0], $barfoo[0]->[1];
or
print $barfoo[0][0], $barfoo[0][1];
or
push @{$barfoo[0]}, qw(
well hello dolly
its so nice to have you back where you belong
);
