Weeellll... more readably, you can use:
1. Named arguments (aka "keywords arguments" -- though a keyword arg
isn't a keyword, of course...)
2. Factory (class methods) (I'm using those parentheses around "class
methods" for precedence, not annotation -- unlike here ;-)
3. Plain old factory methods
4. Factory "functions" implemented as classes with a __call__ method
5. Factory classes with named factory methods (perhaps even class
methods)
6. Plain old factory functions
It's all terribly restrictive, as you can see <wink>
(Yes, I know the OP used the same name to call all the constructors in
his examples -- but that's just an expectation carried over from other
languages)
