Comment (by vbraun):
The `DisplayPreferences` right now does the following:
{{{
sage: prefs = DisplayPreferences()
sage: prefs.text = 'ascii_art' # dot-notation for tab completion
sage: prefs # nice output
Display preferences:
* graphics is not specified
* text = ascii_art
sage: prefs.text? # help documents setting and lists allowed
values
sage: prefs.text = 'foo' # validates
Traceback (most recent call last)
...
ValueError: value must be unset (None) or one of ('plain', 'ascii_art',
'latex'), got foo
}}}
What is IMHO missing is a nice syntax to declare your own preferences and
validation for anything that is not a choice out of a finite list of
strings. I'd rather have tab-completion and built-in help with `?` than
dictionary notation.
