1. Add enum discriminants (#337) …

   * Remove nightly from rustdoc v28 test matrix, since that's now v29. (#332)
   
   * Rust 1.78 is no longer beta. (#334)
   
   * Add enum discriminants
   
   * discriminant clone to lifetime annotation
   
   * complicate test examples
   
   * improved discriminant docs
   
   * hedge bets against placeholder representation

   * finally got implicit discriminants working
   
   * remove sync structs
   
   * move to Cow<'a, str> for discriminants
   
   * Various clean-ups, still fighting closure bounds
   
   *sigh*

   * Actually clone Cow; same error as before, though...
   
   * Got the sucker.
   
   * Wrap up
   
   * Better dcocs for discriminant
