No, it does not. Passing a string a the first of three arguments will still be a type error.
And that is a confusing api. The problem has already been solved by classmethod alternate constructors - they are already used widely in the datetime api. NOT using classmethod constructors is new and confusing for the SINGLE use case of parsing iso formatted dates and times. Why is that special? Why isn't ordinal time special to get into __init__?
