Detailed Description

An undefined that barks on print and iteration as well as boolean
tests and all kinds of comparisons.  In other words: you can do nothing
with it except checking if it's defined using the `defined` test.

>>> foo = StrictUndefined(name='foo')
>>> str(foo)
Traceback (most recent call last):
  ...
jinja2.exceptions.UndefinedError: 'foo' is undefined
>>> not foo
Traceback (most recent call last):
  ...
jinja2.exceptions.UndefinedError: 'foo' is undefined
>>> foo + 42
Traceback (most recent call last):
  ...
jinja2.exceptions.UndefinedError: 'foo' is undefined
