Some more Ruby observations (Re: Comparison between Python and "Ruby")

Here are some random observations from studying the Ruby
source code:
* It seems to have a notion of "tainted" strings, and can
be run in various security modes where certain operations
using tainted strings are disallowed.
* It doesn't use bytecode. The evaluator seems to operate
directly on a parse tree. I don't know what implications
this has for execution speed.
* Here is an interesting little diagram I came across. Note
that Ruby appears to have metaclasses of some flavour or
other.
/*

* +------------------+

* Object---->(Object) |
* ^ ^ ^ ^ |

* OtherClass-->(OtherClass) | | |

* Class---->(Class) |

* +----------------+
*
* + All metaclasses are instances of the class `Class'.
