Humm I say module for representing libs, I have splitted my 
project in various libs, whose I call modules, so, it needs to 
link to each lib I'm using. Although I have implemented most I 
need right now, the current problem is std.array.

std.array increases 500Kb by only including it, so, for keeping 
my build times okay I have been basically ditching phobos...
