You can find the BEAM file path and load it yourself, i think that's
available from MODULE:module_info() reply.
You can parse BEAM file sections using beam_lib standard library
If you for some reason you want to go deep into the code down to
instruction level, or want to write the parser yourself, or you have
non-Erlang code which cannot access beam_lib, here's what's inside a BEAM
