Subject: Hash enumeration returning nulls?

Okay, I must just be too sleep-deprived to see it.  Why  is Hash.each
(and the other enumerables) returning nothing but nils when clearly
the hash is being populated?

$foo={'a' => '1', 'b'=> '2'}

puts $foo.length
puts $foo.nil?
puts $foo.keys
puts $foo.values
puts "\n\n"

$foo.each do |k, v|
  print $k, " and ", $v, "\n\n" # returns 'nil and nil'
end

Thank you.
