this was an interesting reading, thanks for it.
But It happens to me that I'm locked in a mental loop. 
From time to time I think:
- I'll use duck typing.
- I don't need to do that strange things, I'll write a
date_from_string method
- eh, multi methopd dispatch would be nice.. 
- well, duck typing is actually cheking an interface. Why don't we
just use static checked interfaces? what's wrong with a Date-able
mixin ?
- oh, static sux, I'll use duck typing..
