Class IsNotEmpty

                 object --+        
                          |

                                 IsNotEmpty

Checks the value is not empty (a nonblank string, list with items, etc.)

For example:

>>> v = IsNotEmpty()
>>> v("abc")
'abc'
>>> v([])
Traceback (most recent call last):
...
ValueError: '[]' is empty
