It seems like unicodedata is not doing exactly what is expected

public static int digit(char unichr, int? @default = null)

    {
        try
        {
            int? d = GetInfo(unichr).Numeric_Value_Digit;
            if(d.HasValue)
            {
                return d.Value;
            }
            else
            {
                if(@default.HasValue)
                    return @default.Value;
                else
                    throw new Exception();
            }
        }
        catch(KeyNotFoundException)
        {
            if(@default.HasValue)
                return @default.Value;
            else
                throw new Exception();
        }
    }

The code that is throwing the exception is

digit(c, None) where digit is unicodedata.digit

From the Python docs, if a default is provided, it should be returned if the character is undefined.

'Returns the digit value assigned to the Unicode character unichr as integer. If no such value is defined, default is returned, or, if not given, ValueError is raised.'

With https://github.com/IronLanguages/main/pull/74 this is partially fixed. Once these items are pulled in there is still an issue with the return value from time.clock() that pybench is not liking.
