>From reading the disassembly it looks like every time
__arrayExpSliceMulSliceAddass_d is used, the implementation gets put in the
object file instead of just an exterm reference.

main.d:

import module1;

void main() {
    double[] a, b;
    doStuff(a, b);
    a[0..b.length] += b[0] * b[0..a.length];
}

module1.d:

void doStuff(double[] arr1, double[] arr2) {
    arr1[0..arr2.length] += arr2[0] * arr2[0..arr1.length];
}

Command lines:

dmd -c main.d
dmd -c module1.d
dmd main.obj module1.obj

Result:
