Note that the semantics of $\sere{r}$ comes from the
$\mathsf{cl}(\cdot)$ operator defined by~\citet{dax.09.atva}. This
differs from the interpretation of a SERE $r$ in the context of a
temporal formula given by the PSL standard~\citep[Appendix~B.3.1.1.2,
item~7]{psl.04.lrm}: the $\sere{r}$ semantics used here corresponds to
$r!\lor r$ in the PSL standard.
