Static Reflection Support

[nicolasgustafsson]

Static Reflection is near-critical in my field of work(Gamedev), for the ability to annotate member variables and automatic serialization. Current c++ engines mostly rely on hacks to get it working(see unreal header tool); scanning through the docs, I do not find a mention of it.

I realize that this is a very complex language feature and other things have much higher priority, so this is a more general question for the far future: Does the Carbon team have an official stance regarding the inclusion of reflection as a language feature?

If you search for "metaprogramming," it looks like there are tentative plans to support static and runtime reflection through metaprogramming facilities.

Indeed, this seems to include reflection.
I also searched the discord and I get the impression that reflection is planned, but in the far future. That's great! As long as there is some plan for inclusion I'm happy. I was a bit scared that it would be a non-goal as I could not find anything regarding it.

It should be a flexible way to provide traversable Ast programmable macros that run during the preprocessing stage

This will be very convenient for DSL and reflection, etc.
