I think biggest mistake of D enums is merging constants and actual
enumerations into single entity which has resulted in weak typing of
enumerations.
Yeah,
enum E { A = 1, B = 2 }
is the same as:
struct E { immutable A = 1, B = 2; }
(leaving storage aside)
Which for me it doesn't make any sense. Even thinking about the argument
(you should have a big gain to introduce syntax sugar).
enums should be enums, flags should be flags, and manifest constants
should be... well, you got the idea.
enum is to D what const is to C++ :P

I use enums a lot in D. I find they work very

they work was deliberately designed, not a historical

Sorry, I think they ought to have been better. -- Andrei

How they work in languages like Ada.
Ok, brief look at those shows me enums can be converted to a
Pos index but otherwise you cannot associate a numberic value
with them, right?
So if we had that in D, Walters examples would look like..
1)
enum Index { A, B, C }
T[Index.C.pos + 1] array; // perhaps?
type Index is (A, B, C);
d_array: array Index'Length of T;
...
array[Index.B.pos] = t; // yes?
d_array(Index'Pos(B)) := t;
2)
array[Index.A.pos + 1] = t; // yes?
d_array(Index'Succ(A)) := t;
3)
enum Mask { A=1,B=4 } // not possible?
Mask m = A | B; // Error: incompatible operator | for enum
type Mask is (A, B);
for Mask use (A = 1, B = 4);
m : Mask := Mask'Pos(A) or Mask'Pos(B);
Have I got that right?
For a proposal like this to even be considered I would imagine
it would have to be backward compatible with existing uses, so
you would have to be proposing a new keyword or syntax on
enum to trigger typesafe enums, perhaps typesafe is a good
keyword, e.g.
typesafe enum Index { A, B, C } // requires use of .pos to
convert to int 0, 1, or 2.
enum Index { A, B, C } // existing pragmatic behaviour
R
This is the C++ approach with enum class for strong typed enums.

Bugzilla maintenance tonight
Tonight at 11pm pacific time, about 3 hours from now, the D bugzilla is going to go read-only for some much needed maintenance and upgrading. Assuming all goes well, it will come back an hour or so later as issues.dlang.org. That name isresolvable now with an old copy of the db -- don't use it yet as it'll all be wiped out and replaced by a fresh copy of the real db. Redirects will be in place so that old url's send you over to the new site. If things go badly, I'll abort and make d.puremagic.com/issues/ read-write again and try again after resolving whatever issues caused me to give up tonight. Hopefully things will all go smoothly, and apologies in advance if they don't. :) Later, Brad
