- 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.
@Kha I marked the corresponding methods as `protected`.
I currently can't stand `throw_error`, and I am optimistic about

If in the future we need to specify the type we can use
`arbitrary (α := <type>)`
