Is it possible to handle C arrays? Possible implementation linked

8

There's another library called `repr` which claims to handle C arrays properly: https://godbolt.org/z/vbz639n4d. Can this solution be used to handle C arrays properly in boost pfr? Here's a link to...

Hey, I have some pybinded structs, that have a lot of repeating boilerplate: ```cpp struct MyStruct { int x; char c; }; py::class_< MyStruct >(module, "MyStruct") .def_readonly("x", &MyStruct::x) .def_readonly("c", &MyStruct::c);...

PFR does not work with non-copyable aggregates on MSVC 17.10

I was surprised to find out PFR fails to compile the following non-copyable aggregate `Entity` with MSVC 17.10: ``` struct Field final { Field() = default; Field(const Field&) = delete;...

Apparently, the same tricks used here can also be used for reflection on enums, as evidenced by other libraries, for example https://github.com/Neargye/magic_enum Adding enum support should therefore be straightforward.
