Convenient ways to define == and hash about julia HOT 2 OPEN

From the Slack thread, it's notable that other languages like Python (@dataclass: https://docs.python.org/3/library/dataclasses.html) and C# (record: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/record), among others, have seen fit to bring this feature into the language in some official capacity.

Suggests that some standard solution would be a benefit, even if it is not a priority.

I think it would be great if this could be added to Julia. The first question would be if the maintainers are open to such an idea. The design would depend on the functionality one wants to implement. A very modest approach would be a macro defining ==, isequal and hash for a type T based on a list of fields that defaults to fieldnames(T). That wouldn't need much code.

BTW, my package https://github.com/matthias314/StructEqualHash.jl is now in the registry.
