This is changing the cast functions we synthesize and use in all the
code we generate, so yes it is potentially destabilizing.
That said the generated code looks correct to me (and considerably
cleaner). Also, given these functions are really the foundation of a
lot of other code we generate I guess would be unlikely to have these
wrong but still have the testsuite passing clean and Emacs booting up
correctly. Call me optimistic but I'd be pretty confident with this
change...
Not sure I can say more than this, hope it helps.
Regards
Andrea
