* update grammar
* AST nodes and test
* Address self-review comments
- Replace `super` comment with something more explanatory
- Rename `make_user_function`
* add class analysis for uninit functions
* fix ast test after disallowing static uninit funcs
* use std::ranges::find_if
* add tests
* use SUPER constant; add test
* Remove unreachable code leftover from #809
Since #809, the super function is only generated for a class when
registering a parent class, and therefore it will always have a body. A
"No base class defines a constructor" will only occur if super was never
generated, and is handled in the "No function linked through
FunctionResolver" section of semantic analyzer.
* Address review comments
- use std::ranges::move instead of move iterators
- use std::is_same_v<> vs std::is_same<>::value
- use switch vs chained ternary conditionals
* update escript guide, create tests that are in escript guide
* add core-changes
* Error on uninit and defined constructor
* Move methods' FunctionLink construction to builder
This allows the error message for the uninit function to have a "See
Also" that point to the defined function.
* Move error checks for uninit and defined functions
These semantic checks should be in the ... SemanticAnalyzer.
* fix typo in core-changes
