Ruby reserved class method names

In Ruby, are there any methods that are reserved or have default meanings? I recently discovered that initialize is one. Are there any others that I should be aware of when naming my methods? (VI is not giving me the coloring clues that other IDEs give for reserved names.)

In particular, names that have meaning in other languages like run, main, toString, onExit, etc.

Also check out the list of reserver keywords here

If you're working in Rails, you may also want to take a look at this list

Despite nothing prevents declaring methods like public or private, I highly do not recommend doing so with any of the method names defined in core classes, such as Object and Module. Otherwise weird things can happen:

class Message
  def self.private
    puts 'private'
  end

  private
end

Message.private

Output:

private private

Private class method of a class Module was redefined as public.

You can always see a list of the methods implemented by default for every class:

class Try
end

t = Try.new
puts t.methods.sort

EDIT: actually you may also want to look at the private methods (where initialize is):

puts t.private_methods.sort
