Should a range-compliant aggregate type realizing a parser be

In general how should I reason about whether an aggregate type
should be encoded as a struct or class?
You have the example of libdparse that shows that using a class
can be a good idea [1] [2].
For DCD, the parser overrides a few thing because otherwise
completion does not work properly or has scope issues. But TBH
there's not many reasons to use a class otherwise.
