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...
