Mostly whitespace changes, so recommend viewing diff with:
https://github.com/hathitrust/feed/pull/145/files?diff=unified&w=1

The occasional other change is in the form of harmonizing the way we get input args to subs:

sub abc {
    my $self = shift;
    my ($other, $params, $like, $this) = @_;
    # ...
}

... is functionally equivalent to, perhaps more compact than, but not as good looking as:

sub abc {
    my $self   = shift;
    my $other  = shift;
    my $params = shift;
    my $like   = shift;
    my $this   = shift;
    # ...
}

... or in the way default values to arguments are done.

-    my $force_headers            = ( shift or {} );
+    my $force_headers            = shift || {};

Looks very tidy!

I had to look up shift. I learned something new today, thanks!
