1. In the case of Ruby, it wasn't mentioned because I wrote the survey in the spring of 1998 and from what I can tell, there wasn't even a stable version of it at that point.
   
   As for some of those other languages, I'm not familiar with all of them, but I'm sure some aren't mentioned for the same reason as Ruby, and others (like Python) I didn't include for the simple reason that I wasn't very thorough when i wrote it.
   
   (I'm not sure why the date of the paper didn't make it onto the HTML version)
