                Python-like generators in R
              
          
        
      
        
  
      
    A little experiment using restarts.

(And while we’re at it, let’s torture R’s syntax a little.)

In the following we will be using R’s “restarts” feature to implement the
state machine that drives generators in languages such as Python.
Generators allow lazily generating values on demand: a consumer invokes a
generator, and consumes values as they are produced. A new value is only
produced once the previous one has been consumed.
