No, but you can switch to an each() iterator and get at it that way  
(just as you would with an IO object):

$ cat data.csv
one
two
three
$ cat fcsv_example.rb
#!/usr/bin/env ruby -wKU

require "rubygems"
require "faster_csv"

FCSV.open("data.csv") do |csv|
   csv.each do |row|
     puts "#{csv.lineno}: #{row}"
   end
end
$ ruby fcsv_example.rb
1: one
2: two
3: three

Hope that helps.
