The library may work with aggregates that don't satisfy the requirements of `SimpleAggregate`, but the behavior tends to be non-portable.
Boost.PFR's extraction of field name works with a `SimpleAggregate` which variables are able to be declared in any other translation unit.
It's better not to use this feature with anonymous or local structure.
```
struct external_simple_aggregate {
std::string name;
int age;
boost::uuids::uuid uuid;
};
auto v1 = external_simple_aggregate{}; // can be declared outside via `extern`
struct {
std::string name;
int age;
boost::uuids::uuid uuid;
} anonymous; // can't be declared outside
```
Field's name extraction may work with a `SimpleAggregate` that does't satisfy such requirements, but the behavior tends to be non-portable.
Try using `-fpermissive` if you have any issue with it.
