D documentation says:

Do static variables consume any memory in instances, perhaps just for pointers to the variables? Or does compiler automatically convert someObject.someStaticMember to SomeClass.someStaticMember?

Figured it out.

Let's try:

import std.stdio;

class A {
    static int a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z;
}

void main() {
    writeln(__traits(classInstanceSize, A));
}

Prints: 16
Without static: 120
Difference: 104, exactly 26 * int.sizeof

So, the answer is NO, no memory is taken from instances.
