hackcheck fixes the "Carlo Verry hack", which goes like this:

py> object.__setattr__(str, 'lower', str.upper)
py> 'dammit Carlo!'.lower()

It shouldn't be possible to monkey-patch a builtin type; I believe this is to prevent crashes when self has the incorrect layout. Other than that, I find that an arbitrary restriction, except that setattr/attribute assignment prevent an assignment from occurring, it shouldn't be possible to bypass this by calling __setattr__. So if the restriction could be lifted, it should be lifted in both cases.

What specific decimal test is failing?
