But the program doesn't read from IO it's own program. It is a stand alone executable which does no file IO. The compiler on the other hand does IO to inject the file into the program.

Very good! By the way, module name and arguments aren't needed,
so:
import std.stdio;void main(){write(import("q.d"));}
compile with: "dmd q -J."

Any ideas for a shorter version (preferably without using
pointers)?

Re: Quine using strings?
A quine I came up with a while ago, using q{} string notation:
enum s = q{enum s = q{%s};
void main() {
import std.stdio;
writefln(s,s);
}};
void main() {
import std.stdio;
writefln(s,s);
}
