You can use #method


begin
  method :foo # =>
rescue
  $! # => #<NameError: undefined method `foo' for class `Object'>
end

def foo
end
method :foo # => #<Method: Object#foo>

def self.foo
end
method :foo # => #<Method: main.foo>



"hello world".instance_eval do

  method :foo # => #<Method: String(Object)#foo>

  class String
    def foo
    end
  end
  method :foo # => #<Method: String#foo>

  def self.foo
  end
  method :foo # => #<Method: "hello world".foo>

end
