Comment(by hivert):

 The uploaded patch improve family in several ways.

  - first of all the input is now systematically copied to avoid
 modification;

  - now family can handle list and tuple with the class
 {{{TrivialFamily}}};

  - I also corrected the pickling of function when possible and attrcall;

  - since it has nothing to do with combinatorics I moved family to
 sage.set

 Cheers,

 Florent
