This is pretty unremarkable in and of itself, but let's create some data that
contains info for two different people.
Let's try submitting some bad data to make sure form.errors and field.errors
work as expected.

... 'person1-first_name': u'',
... 'person1-last_name': u'',
... 'person1-birthday': u''
... }
>>> p = Person(data, prefix='person1')
>>> p.errors

[u'This field is required.']
>>> p['person1-first_name'].errors
Traceback (most recent call last):
...
KeyError: "Key 'person1-first_name' not found in Form"
In this example, the data doesn't have a prefix, but the form requires it, so
the form doesn't "see" the fields.
>>> data = {
... 'first_name': u'John',
... 'last_name': u'Lennon',

With prefixes, a single data dictionary can hold data for multiple instances
of the same form.

If we use the correct prefix argument, we can create two different forms that
will only use and validate the data for fields with a matching prefix.
>>> p1 = Person(data, prefix='person1')
>>> p1.is_valid()
True
>>> p1.clean_data
