That's what I gathered from Matz's reply on ruby-talk:

I would think they should be "rescue retries" in both cases, and bubble 
out to the rescue block, or they should also be disallowed. I don't know 
which would be more consistent, but I can see valid uses for the block form:

begin
   # body
rescue
   some_array.each {|value| retry if value.is_not_something?}
end

Perhaps eval should stop retries in most cases? eval clouds expected 
behavior for me.
