<lang PicoLisp># In PicoLisp there is no formal difference between abstract and concrete |

# classes, just a naming convention where abstract classes start with a |

# lower case character after the '+' (the naming convention for classes). |

# This tells the programmer that this class has not sufficient methods |

# defined to survive on its own. |
