Hanging loop

ruby-talk
1

This may be a trivial thing, but this simple code seems to
behave oddly:

sequences = Bio::FlatFile.auto(ARGF)
sequences.each do |seq|
puts seq.entry_id
end

Processes all the files I give it but hangs the script after
finishing with the last file. Why would this be?
The code above is from the BioRuby site.
Thanks for any suggestions.

try to give it ^D (Control-D) to say that it must stop to
process. Apparently it's waiting for input from stdin
