That's an instance of a glob operator. I suppose you might be refering to the <> token pair. What about it?

I don't consider the following to show that the glob operator and typeglobs are related.

1. The glob operator can be coded using the "<>" token pair.
2. The "<>" token pair can be used to code the readline operator.
3. The readline operator takes a file handle for argument.
4. A typeglob contains a file handle.
