PEP 313 - Roman numeral literals

[Andrew Dalke]

Mike Meyer:
>     Any literal composed entirely of M, D, C, L, X, V and I characters
>     that does not follow this format will raise a syntax error,

Shouldn't that be a ValueError?

And you should probably add that roman(1000000) will
raise an OverflowError.  But what does roman(0) do?
