|def foo

|
|amodule = Module.new
|amodule.class_eval(data)

|puts(amodule.public_instance_methods)     -> outputs "foo"
|
|amodule.foo                               -> fails saying method is undefined

A public *instance* method means methods are available for their
instances, "amodule" is a module, not an instance.  When you include a
module to a class, and instantiate from the class, you can call "foo".
