    Run a repl. The first parameter is an optional function to call to 
    get a chunk of source code that should return nil for end of file. 
    The second parameter is a function that is called when a signal is 
    caught. One can provide an optional environment table to run the 
    repl in, as well as an optional parser or read function to pass to 
    `run-context`.
