Instance Method Details

#fumble(parent, &block) ⇒ Object

What I’m trying todo is make blocks work inside blocks, and still be able to access the parents attributes, instance_eval lets us do something similar to javascripts with(o){} In this example we cant access ‘you’ inside the cage context how we would like to as its not a local, but see how ‘outside’ works. So we need to catch the missing_method and push send up to the parent, which might be a bit slow but it simplifies the block filter.

@context.fumble(self){        
  puts you   #defined in root context class 
  outside = "outside"        
  cage.fumble(self){
    puts outside
    puts inside #defined in cage class        
    puts you #this errors unless we catch method_missing
  }   
}
