If you read the code, you find the two most important
functions are `regexp-hits-find-hit' and
`search-regexp-in-files'. regexp means regexps!
That there are examples - which work - applied on Lisp
files don't change that.

Now, it doesn't say *one word* about re-parsing or
otherwise analyzing the code with respect imbecile,
ten million times accursed computer science theory.

If you want to do that - just do it! See if I will
come and have 42 degrees of expedition fever and
purposely misunderstand and be all negativistic.
Of course, I will not - and why do you think that is?
