It have to keep it as a private definition for now. We currently only
support duplicate theorems in different modules. Splitters are generated
on demand, and are also used to write code.
This PR includes the following fixes:
- Reserved name resolution inside namespaces
- Equation theorems for `match`er declarations are not private anymore
- Equation theorems for `match`er declarations are realizable
- `foo.match_<idx>.splitter` is now a reserved name
- Add support for reserved declaration names. We use them for theorems
generated on demand.
- Equation theorems are not private declarations anymore.
- Generate equation theorems on demand when resolving symbols.
- Prevent users from creating declarations using reserved names. Users
can bypass it using meta-programming.
See next test for examples.
