Subject: [ruby-talk:18060] Best way to prevent infinite loops...

	Howdy.  What's the best way to prevent infinite loops in Ruby? =20

while some_action
  ...
end

	where some_action is something that could possibly return true=20
forever.  What I've done is something similar to:

loop_count =3D 0
while some_action
  if loop_count > 1000
    raise(RuntimeError, "Too many iterations of main loop")
  else
    loop_count +=3D 1
  end

  ...
end

	Granted that works, it doesn't strike me as very "Rubyish" for=20
two reasons:

1)  I'd think there would be a magic variable that is set already thats=20
an instance of the Integer class that keeps track of how many times a=20
loop has been executed.  Is there and I just haven't found it yet?

2)  The following two work, but aren't very graceful:

loop_count +=3D 1
loop_count =3D loop_count.next

	loop_count.next! would be cool to see, same with loop_count.++


	Thoughts?  -sc

--=20
