Subject: Testing use of binding:  got spurious error message

Hi All,

The program below ends with eval(...) producing an error message, as
shown in the comments at the end of the code.  How can I direct the
offending output to a  "bit bucket"?

Thanks in Advance,
Richard

class MyClass
	def initialize(n)
		@number = n
	end

	def getBinding
		binding()
	end
end

def show(a)
	a.each do |m|
		puts "\t" + m.inspect
	end
end

obj1 = MyClass.new 19
bind1 = obj1.getBinding

obj2 = MyClass.new 84
bind2 = obj2.getBinding

puts "number for  obj1 = " + eval('@number', bind1).to_s
puts "number for  obj2 = " + eval('@number', bind2).to_s

puts "# of methods: " + eval(methods.length.to_s, bind1).to_s
puts "Methods: "
dummy = eval(show(methods), bind1)
puts "That's all folks!"

=begin
# Result:
number for  obj1 = 19
number for  obj2 = 84
# of methods: 46
