D - extending enums
- Pavel Minayev (12/12) Nov 24 2001 I thought it would be fine if enums were extensible:

I thought it would be fine if enums were extensible:
enum Color { red, green, blue };
// somewhere later
enum Color { yellow, cyan, magenta }; // Color.yellow = Color.blue +
1
Not useful as is, but could be very handy if applied
to class hierarchy. So the base class declares the
enum and introduces basic options common for all, and
then child classes add options specific to their
functionality.
Or maybe use the class syntax for enums, with inheritance
and such? A stupid idea, probably, but... =)
