Rename
`mapsto_mapsto_ne`
to
`mapsto_frac_ne`
, and add a simpler
`mapsto_ne`
that does not require reasoning about fractions.
*
Generalize the
`gen_heap`
library to discardable fractions.
+
The
`mapsto`
connective now takes a
`dfrac`
rather than a
`frac`
(i.e.,
positive rational number
`Qp`
).
+
The notation
`l ↦{ dq } v`
is generalized to discardable fractions
`dq : dfrac`
.
+
The new notation
`l ↦{# q} v`
is used for a concrete fraction
`q : frac`
(e.g., to enable writing
`l ↦{# 1/2} v`
).
+
The new notation
`l ↦□ v`
is used for the discarded fraction.
+
The lemma
`mapsto_persist : l ↦{dq} v ==∗ l ↦□ v`
has been added.

See the changes to HeapLang for an indication on how to adapt your language.
+
See the changes to iris-examples for an indication on how to adapt your
development. In particular, instead of
`∃ q, l ↦{q} v`
you likely want to
use
`l ↦□ v`
, which has the advantage of being persistent (rather than just
duplicable).
