  Quorum is a programming language created by Stefik et al. In a 2011 paper, the authors infamously proclaimed:
  
    Results showed that while Quorum users were afforded significantly
    greater accuracy compared to those using Perl and Randomo, Perl users
    were unable to write programs more accurately than those using a 
    language designed by chance.
    
  When I try to run their reference Quorum code using their Quorum download, I get:

      $ java -jar Quorum.jar t.quorum

      The code did not build correctly. Here is a list of errors:
