Better name for instance bypass method?


#1

Ths is used inside an object that clears out most of the Kernel methods
(like BlankSlate). It allows one to get at those methods.

class BasicObject

# ... undefines Kernel methods ...

class Instance < self
  define_method( :method_missing ) do |meth, *args|  # &blk|
    Kernel.instance_method(meth).bind(self).call(*args) # ,&blk)
  end
end

def instance
  @__instance__ ||= Instance.new
end

end

For example:

class A < BasicObject
end

a = A.new
a.class #=> NoMethodError
a.instance.class #=> A

I would be happy with the name “instance” except it does minorly
conflict with Singleton (not the eigenclass kind). Anyone have a better
suggestion for the name. Note, I originally choice “instance” because
of other methods like #instance_variables.

Thanks,

maybe

class BasicObject

 Self = Class.new(self) do
   ...
   ...
   ...
 end

 def Self() @__self__ ||= Self.new end

end

so

o = BasicObject.new
o.Self.p 42

??

in fact, you can even

 def self() @__self__ ||= Self.new end

though that might be confusing, maybe…

 def __self__() @__self__ ||= Self.new end

food for thought.
