Yes, that's what I'm doing currently.

Are you sure that works?
I've just tested the following code with DMD v0.164 (in Linux):

void main()
{
  char[] arr = "test";

  foreach (inout i, inout c; arr) {
    if (i == 0) {
      i++;
      continue;
    }
  }
}

And the compiler says: "foreach: key cannot be out".
Did you use the last version?
