Talk about where macro expansion happens. There is lots of other stuff we should cover here eventually:

  • Hygiene
  • Custom derive and procedural macros and how those work

cc @jseyfried -- can you help on elaborating the list of things that belong here?

Started a simple chapter on macro expansion here: #26

I don't know much about hygiene, custom derive, or procedural macros, but I can write about normal macro_rules expansion...

Ping @federicomenaquintero :)

Are you still interested in writing something up about hygiene or proc macros?

federicomenaquintero commented

I am! Apologies for taking so long; I've been busy with librsvg.

Now that I'm porting gnome-class to syn 0.12, I'm getting a much more practical view of hygiene. I'll write something soon.
