XO0435: a catch-all variant built from a value a named variant has

The catch-all keeps only values no variant names. Built from a value a named variant has, it would be a second spelling of that variant, and it compares unequal to it (equality is by variant). Write the named variant, or E.from(v), which picks it. See core 2.3 and decision 0493.

Example

enum StorageClass: Str {
  Standard = "STANDARD"
  Unknown(value: Str)
}

const S: StorageClass = StorageClass.Unknown("STANDARD")

Fix

enum StorageClass: Str {
  Standard = "STANDARD"
  Unknown(value: Str)
}

const S: StorageClass = StorageClass.Standard
