Homomorphism properties for `bool_decide` + rename (bool_)decide_iff.
- Add homomorphism properties for bool_decide and True, False, →,
↔ - Rename
decide_iff
→decide_ext
andbool_decide_iff
→bool_decide_ext
because_iff
is now used for the above property for↔
. This is also more consistent with other extensionality properties.
