This! This is really the thing I like about D overall! I used to 
prototype in python and either rewrite part of it in C (process 
involving lots of latent rage for missing common features) or 
give up on performance (which, honestly, was most of the time a 
good answer).

In D I feel like I don't have this tradeoff. I start prototyping 
in D putting auto everywhere and not anotating anything and when 
the prototype works I just start cleaning the code, annotating 
it, etc.... The fact that where I used two languages I can now 
use only one is what convinced me (even if, to be fair, the 
prototyping part is way much easier in python... But that may be 
due to the gab of experience).
