- `iModIntro` : introduction of a modality that is an instance of the
`FromModal` type class. Instances include: later, except 0, basic update and
fancy update.
- `iModIntro` : introduction of a modality. The type class `FromModal` is used
to specify which modalities this tactic should introduce. Instances of that
type class include: later, except 0, basic update and fancy update,
persistently, affinely, plainly, absorbingly, absolutely, and relatively.
- `iAlways` : a deprecated alias of `iModIntro`.
- `iNext n` : introduce `n` laters by stripping that number of laters from all
hypotheses. If the argument `n` is not given, it strips one later if the
leftmost conjunct is of the shape `▷ P`, or `n` laters if the leftmost
conjunct is of the shape `▷^n P`.
- `iMod pm_trm as (x1 ... xn) "ipat"` : eliminate a modality `pm_trm` that is
an instance of the `ElimModal` type class. Instances include: later, except 0,
basic update and fancy update.
The persistence and plainness modalities
----------------------------------------
- `iAlways` : introduce a persistence or plainness modality and the spatial
context. In case of a plainness modality, the tactic will prune all persistent
hypotheses that are not plain.
The later modality

Induction
---------
- `iNext n` : introduce `n` laters by stripping that number of laters from all
hypotheses. If the argument `n` is not given, it strips one later if the
leftmost conjunct is of the shape `▷ P`, or `n` laters if the leftmost
conjunct is of the shape `▷^n P`.
- `iLöb as "IH" forall (x1 ... xn) "selpat"` : perform Löb induction by
generating a hypothesis `IH : ▷ goal`. The tactic generalizes over the Coq
level variables `x1 ... xn`, the hypotheses given by the selection pattern
`selpat`, and the spatial context.
Induction
---------
- `iInduction x as cpat "IH" forall (x1 ... xn) "selpat"` : perform induction on
the Coq term `x`. The Coq introduction pattern is used to name the introduced
variables. The induction hypotheses are inserted into the persistent context
