```
plan.Plan.chain(mut, operation: O) -> O::Creates
```

Record an operation that is allowed to share a tmux invocation.

Identical to [`Plan::add`] except that the compiler rejects an
operation whose output could not be told apart from its neighbours'.
Use it to say that intent at the call site; a folding [`Planner`]
reaches the same grouping on its own.

## Example

```rust
use libtmux::plan::{Plan, SendKeys};
use libtmux::PaneId;

let mut plan = Plan::new();
plan.chain(SendKeys::new("%1".parse::<PaneId>()?).text("make").enter());
```
