Draft here:
#232
from fusion.
I need to apply a small patch here: https://github.com/boostorg/fusion/blob/boost-1.80.0/include/boost/fusion/support/tag_of.hpp#L55|
Just like this sample:
https://godbolt.org/z/4ePcWbYqh
It will allow me to integrate PFR as fallback, so thus PFR will be selected when no other reflection not found for T.
This strategy is so simple to implement and will be conviniece for Fusion's users.

@djowel what do you think about this patch above?

What is non_fusion_tag
? [edit, sorry if that was not clear]... I meant why is the link pointing to the non_fusion_tag
?

?
The link pointing to the line that I want to edit. Like this:
- mpl::identity<non_fusion_tag> >::type
+ mpl::identity<typename tag_of_fallback<Sequence>::type> >::type
And also this before the line(in the detail
namespace):
template<typename Sequence, typename Active=void>
struct tag_of_fallback
{
typedef non_fusion_tag type;
};

Ah. Makes sense. Go for it.
