which is equivalent to
$HOA{ $key } = [ 'a', 'b', 'c', 'd' ];
and can also be written as
$HOA{ $key } = [ 'a' .. 'd' ];

Pushing is done on arrays, at the top.
You have an array reference in $HOA{ $key }, so first you need to
dereference it, by applying @{ }.
push @{ $HOA{ $key } }, 'element';
If by "into" you meant an insertion at the start or middle, read the
documentation of shift (`perldoc -f shift`) and about array slices in
perldata (`perldoc perldata`).
