When I use a column with `hll` type as a field in `GROUP BY` clause, I get the error:
```
ERROR: could not identify an equality operator for type hll
```
Here's a small repro:

With C++20 it's possible to default comparison operators. With `has_unique_object_representations` and an intrinsic to detect if type is trivially equality comparable (it has `default`ed `operator==` …

It would be better to use enum members (like `LawType.SCALAR_ISOTROPIC_LAW`) with the equality operator rather than strings (like `"scalar isotropic law"`), so you can't introduce an error by copying …

While using the `In` and `NotIn` rules, I've noticed that their implementations are inconsistent. The former uses DeepEqual to verify equality, whereas the latter uses the equality operator. In cases …

For undirected problems (CVRP with symmetric distances), we can have different representations of the same solution by reversing routes. Related to #101, which considers the distance between such inst…

Since I know you're rewriting the LINQ parser for v4, I would like to suggest a refactoring that would simplify query processing and fix some edge cases.
Specifically this is about the equality `Ex…

This is as a result of the refactoring to meet type-safe equality operators

### Background and motivation
The bfloat16 type provides the same number range as the 32-bit IEEE 754 single-precision floating point type, but with a reduced precision (24 bits -> 8 bits). This is…
