    (dofile path &keys {:read read :parser parser :source src 
    :evaluator evaluator :expander expander :env env :exit exit})

    Evaluate a file and return the resulting environment. :env, 
    :expander, :evaluator, :read, and :parser 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.
