As others have pointed out, nope.

Just like to share that I tend to do the opposite sometimes, and that
isn't so difficult:

def method!
	# mutate the object
end
def method
	result = self.dup
	result.method!
end

Well, this works if the intent and behaviour of dup isn't at odds. And
you could probably make an evil-eval module function for a shortcut that
makes the non-mutator version of the method for you.
