It was annoying to get my head around this. the 'magic' part of it
holds true and makes it confusing.
for the longest time, i would just print $var, ref $var and other stuff
to STDERR to try and get my head around it
I never quite did completely understand it, but doing the above trained
me to code for it

When exactly is this ref used? AFAIK $_[0] will never be a reference.
it will when you use the :method attribute :)
in short, it's magic - run the handler and you'll see that $r is _not_
the
first argument to that handler, but the second.
