Yes.

There are more uses for traditional `for` loops than just looping over 
integers or ranges.

The use case I had, I needed to rewrite into a sequence. Hm... Let me 
find the change:

```swift
for var i = 0; (gridOrigin.x + CGFloat(i) * subGridSpacing.width) * 
scale < bounds.width; i += 1 {
...
```

I wrote a "for generator" sequence type that accepted a lambda for the 
condition. It now looks like:

```swift
for i in forgen(0, condition: { (self.gridOrigin.x + CGFloat($0) * 
self.subGridSpacing.width) * self.scale < self.bounds.width }){
...
```

This is just a hack, and not a full replacement. It takes an initial 
value and an increment (by default 1), and only works with Int.

Honestly, it was a long time ago (heck, they probably removed more 
features and this won't compile now). There might be better ways. And I 
probably would have been fine with swift never having for loops. But to 
start out with them, and then remove them, seemed unnecessary.
