  arc> (on-err (fn (c) 'oops) (fn () (do1 (/ 8 0) (prn "here"))))
  here
  oops

Probably?

Since the division fails, do1 never gets to execute the prn. Both results shown in the original post seem right to me.

The comment specifically bemoans that the code after the error isn't executed - and that this particular fact isn't, exactly, what pg/rtm intended.

Yeah, I think the only scenario that makes sense is that on-err was supposed to do a CL-like restart without any actual condition system.
