Feature #6372: More specific error for uncaught throw
https://bugs.ruby-lang.org/issues/6372#change-27159

I have this method:

=begin
  class Symbol
    # Does the block throw the symbol?
    # 
    def thrown?
      catch(self) do
        begin
          yield
          true
        rescue ArgumentError => err     # 1.9 exception
          false
        rescue NameError => err         # 1.8 exception
          false
        end
      end
    end
  end
=end

But it was recently pointed out to me that the rescue of ArgumentError and NameError is not good enough b/c they might rescue an unrelated error of the same type. So to make this right there needs to be a more specific error. Perhaps `class ThrowError < ArgumentError`.
