Hello,

This is a summary of ruby-dev ML in these days.

---- ruby-dev #18281-18319 (2002-09-14 ... 2002-09-21) ----

[ruby-dev:18285] rubicon on EWS4800

  Koji Arai posted a patch to run rubicon on NEC EWS4800 workstation.

[ruby-dev:18292] escaper.rb

  Akinori Musha introduced escaper.rb(*), which provides classes for
  escaping strings.

[ruby-dev:18314] class nest in module_eval

  Minero Aoki noticed an unconsistency behavior(*,**) in ruby-1.7.
  ruby adapts ruby_class to check if a class is defined. On the other
  hand, ruby defines the class with ruby_cbase. Both of their values
  are ususally the same. In module_eval, the value of ruby_class become
  a receiver of module_eval and the value of ruby_cbase keeps unchanged.
  He proposed that behavior for constants and one for class should be the
  same. Matz agreed with him.

  (*) Example 1: The class T will be redefined with a warning.
  class A
    class B
      class T
        puts "A::B::T   = #{self.id}"
      end
      ::A.module_eval {
          class T
            puts "A::B/A::T = #{self.id}"
          end
      }
    end
  end
  puts "A::B::T   = #{A::B::T.name} (#{A::B::T.id})"

  (**) Example 2: Definitions in the class T in module_eval will be
                  added to an already defined class.
  class A
    class T
      puts "A::T      = #{self.id}"
    end
    class B
      class T
        puts "A::B::T   = #{self.id}"
      end
      ::A.module_eval {
          class T
            puts "A::B/A::T = #{self.id}"
          end
      }
    end
  end
  puts "A::T      = #{A::T.name}    (#{A::T.id})"
  puts "A::B::T   = #{A::B::T.name} (#{A::B::T.id})"
