I find myself frequently implementing the same `(x, y)` pattern:

```
let rectangleSizes = seq {
    for w = 1 to width do
        for h = 1 to height do
            yield (w, h)
}

```

Wouldn't out there be a simple one-liner for this, by chance? Of course I could just write this very same function in just one line, but I feel its readability would suffer quite a bit:

```
let rectangleSizes = seq { for w = 1 to width do for h = 1 to height do yield (w, h) }

```
