`sleep(1000)->100.0%panic`  ，panic is not executed

```go
func (t *terms) eval() (interface{}, error) {
	t.mu.Lock()
	defer t.mu.Unlock()
	for _, term := range t.chain {
		if term.mods.allow() {
			return term.do(), nil
		}
	}
	return nil, nil
}
```

`return term.do(), nil` causes the following term to not be executed
