I don't mean p is actually a pointer, I just mean p is the offset after
your (l=2 s=3) stuff that you matched with a regexp in your original
example.

Why don't you read some of the Emacs library code?  That is basically
how I learned Lisp.  Or, CL has a real package system so you can do more
serious encapsulation.  So you could read a CL book and apply the
techniques to Emacs Lisp as best you can.
