That is really odd, because it should be one or the other, but not both. For example: 
sub odd_args
{
     my ($this, $args) = @_;
     print $args->{x},$/;
}

sub odd_args
{
     my ($this, %args) = @_;
     print $args{x},$/;
}

Are you sure there wasn't a prototype?

Update: As pfaut pointed out, this seems to be some kind of automatic casting that 5.6.1 could do, though I can see why this "feature" was removed.
