## Side-effects
Importing Iris has some side effects as the library sets some global options.
* First of all, Iris imports std++, so the
[std++ side-effects](https://gitlab.mpi-sws.org/iris/stdpp/#side-effects)
apply.
* On top of that, Iris imports ssreflect, which replaces the default `rewrite`
tactic with the ssreflect version. However, `done` is overwritten to keep
using the std++ version of the tactic. We also set `SsrOldRewriteGoalsOrder`
and re-open `general_if_scope` to un-do some effects of ssreflect.
