- 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.
