```
libtmux::capture_lines(typename Text, Text &&) -> typename Text
```

The lines are views into the text, so text that dies at the semicolon takes them with it — and `pane.capture()` returns its output by value, which makes `capture_lines(*pane.capture())` the natural thing to write and a use-after-free to run.

Deleted for an rvalue string only: an lvalue string converts as before, and so does a literal.
