* Add alert messages to deprecation annotations (#47).
* The solution using ephemerons introduced in v0.8.7 for attaching
  custom data to formatters has unreliable performance characteristics
  in some usage scenarios. Namely use of `Fmt.styled` with
  `Fmt.[k]str` heavy code as those rely on `Format.{k,a}sprintf` which
  allocate one formatter per call. 
  
  Hence we subvert again the `Format` tag system to do dirty
  things. However since as of 4.08 tags became an extensible sum type
  we can keep our dirty things entirely internal.

  Thanks to Thomas Leonard for reporting and David Kaloper Meršinjak
  for further investigations (#52).

  to compose with other errors. Thanks to Thomas Leonard 
  for the patch.
