If I learned nothing else from this thread, I learned that I *never* want to
screw around with PHP. ;)

Python has the nice property that you're not allowed to modify builtins, so no
one can ever make your Python code do anything other than:
>>> foo = 'abc'
>>> foo[0] = 65
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
TypeError: object does not support item assignment
I wonder what people think about Ruby, which, I understand, does allow you to
modify builtins. Can anyone tell me if you could make Ruby strings do the
horrible coercion that PHP strings do?
