Was a decision ever made about incorporating one of the unit testing 
frameworks (either RubyUnit or Test::Unit) into the Ruby 1.7 
distribution? I don't mean as an add-on package, but a standard part of 
the library. It seemed at one point that Test::Unit had been declared 
the heir apparent to RubyUnit (see e.g. ruby-talk:23904), and I thought 
I saw posts that indicated that it was being incorporated into the Ruby 
standard library.
