  object.methods #=> returns array of method names

And since Classes and Modules are objects you can call the methods method 
on them as well (though you may want to call 'instance_methods' depending 
on what you're looking for).

You want'em sorted?

Looking for a particular method?

  object.include? "methodname"  #=> returns true of false

Oh, wait ...oops, sorry wrong list ;-)
