@GCHQResearcher1337 any reason you didn't implement the labelling for
`repeat()` as described in the JIRA issue:
```text
repeat('a',out('knows').repeat('b',out('parent')))
```
As the issue states, it's usage would probably be rare, but marko had that
intention when he created the ticket so I thought I'd ask about it (also marko
has been lurking about and mentioned it to me last night :smile: ).---
