Thanks for your reply. As for cast, I seems not to have any 
option, because to! doesn't work as I would expect it. It would 
return me an array of numbers, instead of a string; So I kept the 
cast here, since I certainly know what it's doing -for now-.

I generally use immutables, you caught me, here :-). As of main 
and return, I was not aware we could just ignore them if we 
didn't need them. I love explicit programming.

However, I'm still stuck with toStringz(). Since it returns an 
immutable(char[]), I can't find how to pass it to Socket.send(), 
and I do not seem to be able to cast away the immutable :-s
