What happens when both empty and non-empty fields appear ? E.g. would

    'I love {} with {1} and {} with {1}'.format('bacon', 'eggs', 'sausage')

return 'I love bacon with eggs and eggs with eggs', or it would be
smarter and see that 1 is used explicitly and skip over it, giving 'I
love bacon with eggs and sausage with eggs' ?
