[erlang-questions] Unable to call functions that are in a module in the same location

[Yves S. Garret]

This is it:

-record(sensor,
  {id, name, cx_id, scape, vl, fanout_ids = [], generation}).
-record(actuator,
  {id, name, cx_id, scape, vl, fanin_ids = [], generation}).
-record(neuron,
  {id, generation, cx_id, af, input_idps = [], output_ids = [], ro_ids =
[]}).
-record(cortex,
  {id, agent_id, neuron_ids = [], sensor_ids = [], actuator_ids = []}).
-record(agent,
  {id, generation, population_id, specie_id, cx_id, fingerprint, constraint,
   evo_hist = [], fitness, innovation_factor = 0, pattern = []}).
-record(specie,
  {id, population_id, fingerprint, constraint, agent_ids = [],
   champion_ids = [], dead_pool = [], fitness, innovation_factor = 0}).
-record(population,
  {id, polis_id, specie_ids = [], morphologies = [], innovation_factor}).
-record(constraint,
  {morphology = xor_mimic, neural_afs = [tanh, cos, gauss, abs]}).
