<p>It may also work if you create a "generic" extension that can
only be applied to strings.</p>
<p>Then i'm guessing that you will not need to specify the type on
the use.</p>

But I was hoping it would do the right thing:<br>
<br>
let a = s.deleting(prefix: "foo")<br>
if let b = s.deleting(prefix: "foo") { }<br>
<br>
But it finds these ambiguous, and I'm not sure how to
specify which I want.<br>
<br>
I'm having trouble googling for an answer on this. Some
answers around generics, but that doesn't apply in this
case.<br>
