struct S {
    @property size_t length() const {
        return 1;
    }

    S opSlice(size_t lower, size_t upper) { assert(0); }

    alias length opDollar;
}

void main() {
    S s;
    auto num = s[0..$];
}

This is crashing dmd, do you want me to open a new bug report?


static struct Foo {
    int[] opSlice(int a, int b) {
        return [a, b];
    }
    int opDollar(int dim)() {
        return dim;
    }
}
void main() {
    Foo array;
    array[0 .. $];
}



Assertion failure: 'd' on line 1401 in file 'dsymbol.c'
