Subject: Re: Continuation - where does it continue

Hi,

this finally cleared up Ruby's continuations for me too.

Would this be the effect you're after?
# code
def cc
   puts "do A"
   puts "----> 1. #{caller}"
   cont = callcc { |cont| return cont}
   puts "----> 2. #{caller}"
   puts "do B"
end

puts "calling cc"
if cont = cc()
  puts "doing other stuff"
  cont.call() if cont
  puts "end of work"
  puts
end

#output
__END__
calling cc
do A
----> 1. continuations.rb:10
doing other stuff
----> 2. continuations.rb:10
do B
#end

I'm curious - what problem are you trying to solve?

Regards,
Sean
