Golang's reflection is severely limited by design, so that there is nothing to restrict during compilation. On the other hand, you lose out on powerful tools such as C#'s System.Reflection.Emit. To note, the biggest library limited by AOT compilation, ASP.NET (which does still work with it if you design around the limitations), is being updated to work better with it (and source generators play a big part of that).
