Hello Antoine,

Thanks for your quick answer:

and
--> a = mlist(["aBcD", "id" "id2"], 1, 2);
--> a==a
  ans  =
   T T T

OK: so
a) there is actually a default equality definition
b) it is actually type+fields-wise
c) it looks not documented: none of the list, mlist, tlist, overloading, 
comparison, and equal pages indicate it.
d) it is overloadable:

function  r= %aBcD_o_aBcD(a, b)
     r  =  typeof(a)==typeof(b);
     af  =  fieldnames(a);
     r  =  r  &  and(af==fieldnames(b));
     for  f  =  af'
         r  =  r  &  and(a(f)==b(f))
     end
endfunction

--> a==a
  ans  =
   T

Thanks
Samuel
