In this program the Foo struct is large, so I use ref to avoid its copies. I also use const because I want to make sure (and document) the two loops will not change the matrix contents:


struct Foo { int[1000] a; }
void bar(ref Foo x) {}
void main() {
    auto m = new Foo[][](3, 3);
    foreach (const(Foo[]) row; m)
        foreach (ref const(Foo) x; row)
            bar(x);
}


But I'd like type inference there, and be able to write something like:

struct Foo { int[1000] a; }
void bar(ref Foo x) {}
void main() {
    auto m = new Foo[][](3, 3);
    foreach (const row; m)
        foreach (ref const x; row)
            bar(x);
}


With DMD 2.055beta3 this gives:

test.d(5): no identifier for declarator const(row)
test.d(6): no identifier for declarator const(x)

You're kidding me right?  This is the THIRD time you've reported this exact bug.

Just don't forget to do a quick search first next time!
I know you have over 200 enhancement requests open, but it might be worth going
through and checking they all still make sense.
