Mr. Woods told me about Ruby many times. At that time, I never which to try it. I am not fluent with C++ enough so why bothering with other languages. (Hell, that's true. I just cope `dynamic_cast' and love it only recently.) Today, after reading Bruce Eckel's blog, there are many many concept I have never heard of, e.g., coroutine, metaclass, continuations, Rail, etc. What the heck.

Have to give them a try.
