Parse CSV file with header fields as attributes for each row

I would like to parse a CSV file so that each row is treated like an object with the header-row being the names of the attributes in the object. I could write this, but I'm sure its already out there.

Here is my CSV input:

"foo","bar","baz"
1,2,3
"blah",7,"blam"
4,5,6

The code would look something like this:

CSV.open('my_file.csv','r') do |csv_obj|
  puts csv_obj.foo   #prints 1 the 1st time, "blah" 2nd time, etc
  puts csv.bar       #prints 2 the first time, 7 the 2nd time, etc
end

With Ruby's CSV module I believe I can only access the fields by index. I think the above code would be a bit more readable. Any ideas?
