Providing a object-specific class scope?

Ruby
1

Is it possible to do something like this with Ruby?

#!/usr/bin/env ruby

class Scope
def hello_world
puts “Hello World”
end
end

scope = Scope.new

transaction = class << scope; self; end;

Without making Scope#hello_world a class method, can we make this work

somehow?
eval “hello_world”, transaction.send(:binding)

The idea would be to provide the ability to write something along the
lines
of transaction.send(:include, MyModule) without affecting the original
instance of scope, while still providing access to all methods.

Kind regards,
Samuel

I hate to answer my own question, but after some more experimentation I
found that this works pretty well:

#!/usr/bin/env ruby

class Transaction
def scope(helpers)
helpers.class_eval do
Proc.new {}
end
end
end

module Helpers
def self.hello_world
puts “Hello World”
end
end

transaction = Transaction.new

eval “hello_world”, transaction.scope(Helpers).binding

I hope this may be useful to others.

Kind regards,
Samuel

Clearly I shouldn’t be coding at 4am. The above example doesn’t actually
work correctly =) I’m going to shut up and go to bed now.
