If I understand your problem correctly, you can use Python double-star syntax.
people = [ { 'title':'Mr','name':'Darth','lastname':'Vader' },
{'name':'Luke','lastname':'Skywalker'} ]
for person in people:
Person(**person))
It will "open" the dict into keyword arguments, if the argument is not
there (like in your second item in the list, that is missing title),
it will simply not pass it, making Elixir create it as None (if the
field is not required).
