Hello,

I wanted to use skipOver on my input range, but I ran into an 
error that it needs a .save method in the range.

I can't give that because it's a generator function that catches 
yield()s, I can't save the state of that.

What I wanted to simplify is this:
```
void skipWhite()
{
   while(!scanner.empty && scanner.front.src.all!isWhite)
     scanner.popFront;
}
```

Is there a way to do it nicer with Phobos?
Or do I have to write a popFrontWhile() template function for 
this? (And try not to forget it's name in the future ;)

You can use `find` with a negated predicate: `find!(x => 
!x.front.all!isWhite)`

Perfect, Thank You!

I guess skipOver is more complex, it looks ahead, it's not just 
for one element, that's why it needs a ForwardRange.
