Description
The new [enumeration types](https://docs.djangoproject.com/en/3.0/ref/models/fields/#enumeration-types) are great but can't be used in Django templates due to their being callable. For example this doesn't work:
{% if student.year_in_school == YearInSchool.FRESHMAN %}
This is because YearInSchool, being a class, is callable, and Django Templates always call callables with no arguments. The call fails because the required value argument is missing.
The easy solution would be to declare do_not_call_in_templates = True on the various Choices classes.
