• The exported types are not documented (mostly).

CONTRIBUTING.md

be thoroughly documented (README, pkg.go.dev doc comments, etc.) in the English language, so everyone is able to understand the project's intention and how it works. All public functions and types should have a Go-style documentation header;

@yassinebenaid I added some docs. Could you review it again? Thanks

This is not in a right category

I see another Copier one is in the group, DeepCopier. Could you point out which is the one more suitable?

[yassinebenaid]

Should we add a new category called Reflection (or similar) under which all reflect based projects will be listed ? @phanirithvij

Examples:

• Deepcopier - Simple struct copying for Go.
• copy - Package for fast copying structs of different types.
• gpath - Library to simplify access struct fields with Go's expression in reflection.
• objwalker - Walk by go objects with reflection.
• reflectutils - Helpers for working with reflection: struct tag parsing; recursive walking; fill value from string.

And

• go-deepcopy - Fast deep copy library.
