Given:
enum Numbers {
        zero = 0,
        one = 1,
        two = 2,
        FILE_NOT_FOUND = 101
}

dmd -X gives:

   {
    "name" : "Numbers",
    "kind" : "enum",
    "line" : 20,
    "baseDeco" : "i",
    "members" : [
     {
      "name" : "zero",
      "kind" : "enum member",
      "line" : 21
     },
     {
      "name" : "one",
      "kind" : "enum member",
      "line" : 22
     },
     {
      "name" : "two",
      "kind" : "enum member",
      "line" : 23
     },
     {
      "name" : "FILE_NOT_FOUND",
      "kind" : "enum member",
      "line" : 24
     }
    ]
   },



Good, but not great: it doesn't include the value given, so there's no way when reading this to know that FILE_NOT_FOUND is not equal to three.

It should include the value, if at all possible
