Having had heavy experience with Python, and having used D since 
D1, I would tell the contrary, that's easier to handle null 
exception with D. That's only experience based, naturally, I 
don't pretend this to be science.

Going down the hill, we should then love PHP, as it's mantra 
seems to be "go marching in", and we all know what an horrible 
mess it is.
