Dunno. You'll have to ask the author :)

Well,
foreach my $name (@{ $ary_ref = $dbh->selectcol_arrayref($statement)})
{
...stuff;
}
would, since variable type-prefixes can be followed by a "block" whose
value is a reference to the type indicated by the prefix.
But, I'd prefer:
$ary_ref = $dbh->selectcol_arrayref($statement)
foreach my $name (@$ary_ref)
{
...stuff;
}
