variation_feature objects have a strand just like all features in Ensembl -
most are on the forward strand (as this makes our life easier!) but many are
also on the reverse strand.

As I mentioned earlier, you can check this using:

$vf->seq_region_strand

which will return a value of 1 (forward) or -1 (reverse).
