Re[1]: [CEDET-devel] [eieio] :before and :after methods not called

Howdy all,

  I have indeed finally found the reference to how these methods
should be called in my favorite CLOS hyperspec.  I was oblivious to
the specific paragraph before.

http://www.lispworks.com/documentation/HyperSpec/Body/07_ffb.htm

  It's sort-of in the middle-ish of that page with three sub-bullets.

  Anyway, there are some pretty subtle changes in EIEIO required to
manage this, plus changes to code depending on various dependant
behaviors for this, and some of the other email invovled.

  As a side effect, if I can get things working correctly, I will
probably post yet ANOTHER beta of cedet to allow some recovery on
dependent packages as the effects of the new error messages have
been somewhat devastating in my own code.

  As I get some of this stuff checked in, I'll post about the changes
and how to solve problems that may be caused, though that may not be
today. :(

Thanks for the detailed look-up of the actual rules.
Eric
