=begin
class Enum
include Enumerable

   def initialize
     @elements = [self]
   end
   def each
     @elements.each {|e| yield e}
   end
 end

 Enum.new.join

This code hangs for a second or so then complains:

$ ruby -vw /tmp/inspect_tbl.rb
ruby 1.9.2dev (2009-07-05 trunk 23958) [i686-linux]

Drat. I filed this against the wrong version; it should be against trunk. :-(

Apologies if this is obvious, but I just noticed that if you rescue the aforementioned exception then say File.join(['a','b','c']), File will raise an exception "`join': recursive array (ArgumentError)".
