#alias_singleton_method(new_msg, old_msg) ⇒ Object

it simply alias singleton(instance) method

# File 'lib/ludy/kernel/singleton_method.rb', line 12

def alias_singleton_method new_msg, old_msg
  self.class.__send__ :alias_method, new_msg, old_msg
end

#cut(target, &block) ⇒ Object

def cut target, &block
  (class << target; self; end)
end

#deep_copy ⇒ Object

common idiom for:

Marshal::load(Marshal::dump(self))

def deep_copy
  Marshal::load(Marshal::dump(self))

#define_singleton_method(msg, &block) ⇒ Object

it would be defined if RUBY_VERSION < ‘1.9.0’, see rdoc in ruby 1.9

def define_singleton_method msg, &block
  self.class.__send__ :define_method, msg, &block
end

#defun(name, *args, &fun) ⇒ Object

you can use defun for overloading(ad-hoc polymorphism), multi-method, pattern matching, and perhaps others?

#id(a = nil) ⇒ Object

id returns self

#tap {|_self| ... } ⇒ Object

it would be defined if RUBY_VERSION < ‘1.9.0’, see rdoc in ruby 1.9

Yields:
