BAMFCSV - BAMF, your data's here!
Rivaling the amazing transitive powers of Nightcrawler, Jon Distad and I decided to tackle the problem of parsing CSV rapidly under Ruby 1.9. "Aha!" you might be saying, "FasterCSV was already rolled into the stdlib in Ruby 1.9! Why would I need a gem to handle it?" Well you have a very good point there, FasterCSV was a good response to the performance of the old 1.8 stdlib CSV parser. However there are still cases where it doesn't quite go fast enough.
