What are people using Ruby for?
108937 [j_m_h@co .n ] I'm not currently a Ruby user but have heard about it for a

|   109009 [jamesUNDERBA] I'm pretty sure that "beat this" was a facetious, not serious, challenge.
|   109020 [hal9000@hy e] That makes more sense than some of the RCRs I have seen.

Random variable library?
