Well, you didn't get such an error with *that* code, as it doesn't use
each_pair. You can use Hash.each(), but in that case, instead of getting
the key and value directly, each item iterated is an array of form [ key,
value ]. So you might use this variation:
<%
@ospf.sort.each do |pair|
instance = pair[0]
instance_data = pair[1]
-%>

Yes. Hash.each_pair() is new in Ruby 1.9.
Hash.each() exists in 1.8. I prefer it to Hash.each_slice() for this
purpose, though the two would work similarly, because the meaning and
behavior of the Hash.each() are clearer to me.
