That mimics the example (where the retry is unconditional), but

I'll be surprised if more complex examples can't be similarly converted
fairly easily. That was kind of my point. I meant the code to say, take
a step back and think what is this trying to do?


My code walks an array, and may change the current element, which is allowed
without breaking the iteration.

I have also a special case where i have to change a whole subsection of the
array, this was the case where i used 'retry'

eg
ary.each { |e|
case e
when foo
ary[ary.index(e)] = foo(e)
when bar
when ...
when baz
ary[ary.index(e), 12] = [flublu]
retry
end
}

Sure, i could use map or many other ways, my code is quite ugly anyway.
I was just surprised by the change of behavior.

I don't see the point in removing capabilities from the language (restarting
an iteration from within), but I can sure live with it.
