Description bearophile_hugs 2014-04-25 14:10:21 UTC 
I think both the following should compile:


int[1] foo1(int[1] a) {
    a[] += 10;
    return a;         // OK.
}
int[1] foo2(int[1] a) {
    return a[] += 10; // Error.
}
void main() {}


DMD 2.066alpha gives:

test.d(6,16): Error: cannot implicitly convert expression (_arrayExpSliceAddass_i(a[], 10)) of type int[] to int[1]

I think the good way to solve this bug and others (and to improve D language usability in other ways) is with the enhancement of Issue 13228
