Also global variables are (conceptionally) kept here. |

As you will notice, this is NOT a Dictionary |
|
47 |
- my implementation of globals is totally different |
|
48 |
(due to the need to be able to access globals from c-code as well). |
|
49 |
However, it provides the known enumeration protocol. |
|
50 |
It may change to become a subclass of collection at some time ... |

If lazy is true, no code is generated for methods, instead stups |

are created which compile themself when first executed. This allows |
|
1967 |
for much faster fileIn (but slows down the first execution later). |

1968 |
Since no syntax checks are done when doing lazy fileIn, use this only for |
|
1969 |
code which is known to be syntactically correct. |

1970 |
If silent is true, no compiler messages are output to the transcript. |

Giving nil for silent/lazy will use the current settings. |
