Do you mean:

m = Module.new

=> #<Module:0x1018a040>

m.name

=> ""

m.class_eval { def foo; puts "bar"; end }

=> nil

o=Object.new

=> #<Object:0x101c8248>

o.foo

NoMethodError: undefined method `foo' for #<Object:0x101c8248>
        from (irb):10

o.extend m

=> #<Object:0x101c8248>

o.foo

bar
=> nil

Kind regards
