Interceptors (new C# metaprogramming feature) to fuel DapperAOT development

I've rewritten the title to be more informative. Key point IMHO is a new metaprogramming feature that enables development of a more elegant DapperAOT version.

Original title, I think, is a bit too generic project status update:

  Announcement/Input - DapperAOT progress and Dapper API / feature update

English is not my native language, so I'm not sure it's a good title for HN. Any suggestion to improve it are welcome.

I'm having trouble finding any information from MS on interceptors. Can you link something about them?

https://github.com/dotnet/csharplang/issues/7009

[Proposal]: Interceptors #7009

> An interceptor is a method which can declaratively substitute a call to itself instead of a call to an interceptable method at compile time. This substitution occurs by having the interceptor declare the source locations of the calls that it intercepts. This provides a limited facility to change the semantics of existing code by adding new code to a compilation (e.g. in a source generator).

Sound like Spring AOP stuff without reading more

Without interceptors, source generators can only add new code, but cannot modify any existing code. Interceptors enable method call substitutions.
