Well, $ is supposed to match the end of the line, so I don't think $$ is
all that meaningful. Maybe it will match model$ at the end of the line,

That means those two things have to have the same method name. It's to
ensure that if you merge foo into "fooGen" that you can have fooGen be
private even though foo is public.

read, but that's about it...
