    (dofile path &keys {:expander expander :env env :exit exit :source src
    :evaluator evaluator})
    
    Evaluate a file and return the resulting environment. :env, :expander,
    and :evaluator are passed through to the underlying run-context call.
    If exit is true, any top level errors will trigger a call to (os/exit
    1) after printing the error.
