Someone always asks this question - how do you check types in Ruby? (*Hint: Ruby use dynamic typing) This typical newbie question would ask this and be answered with various levels of helpfulness - typically none - sadly.
However this thread is just beautiful in its helpfulness. http://groups.google.com/group/comp.lang.ruby/msg/eb4b49a511e44be6?hl=en
What happended snarkiness, or Slashdot / Youtube style comments? All this helpfulness must come from somewhere. I blame Twitter.
