Sure, but their type is char[]. Which is silly, because there are no immutable arrays in D. Meaning that the following would pass the compiler but produce a segfault or astonishing behaviour depending on whether text segments are read-only on the target platform:

char[] foo(int x, char c) {
    char[] poit = "hurble burble";
    if(x < poit.length) poit[x] = c;
    return poit;
}

I.e. the string literal would be modified through the array access. Which isn't so good.
