Dolphin comparable to VW valueNowOrOnUnwindDo:

I'm reading the Brant-Foote-Johnson-Roberts' "Wrappers to the
Rescue" from

  http://www.laputan.org/brant/brant.html

Does Dolphin have a method comparable to VW's "valueNowOrOnUnwindDo:"?
I looked around exception handling, Process, and the ProtoObject but
nothing looked comparable.

Thanks, and sorry if the Buckaroo Bonzai quote is appropriate:

  "If it was a snake, it'd have bit me!"

 which is, believe it or not, a complete transcript of the BB
 movie.  Gee, and I thought Smalltalkers were fixated.... (;-)} ]

#ensure: is the equivalent message. It is part of the ANSI standard, but
when the paper was written VW didn't define it.

Thanks, John.
