function parameters?

//Easy (prototype level)
function  create_user(  login, password ) { .... }

// v1.0
function  create_user(  login, password,  name, profile ) { .... }


// v3.0
function  create_user(  login, password,  name, profile,  system,
machine,  lang, is_admin, is_sysop,  listObservers, accesers,
multiplayRoles ) { .... }

// v9.0
* insert monstruosity here *

at some point, adding more parameters make the function unusable,
better use some structure, oop, or any other solution

create(  {  name: port.Name, profile: port.defaultProfile, lang: "en_EN" } );
create(  {  login: "reserver", is_systemcreated: true } );



Bonus reference:
"databases" made of hashes key / value, that have grown to gigabytes of data.
phone = ["aud_aux_DOCTOR_phone_" . id_doctor ]
