 Explained in current marketing speak, `tink_macro` is *the* macro toolkit ;)

-You can find a type map, i.e. a map where the keys are `haxe.macro.Type`, in `tink.macro.TypeMap`. It's pretty much an ordinary map. Currently, it relies rather strongly on [`haxe.macro.TypeTools.toString()`](http://api.haxe.org/haxe/macro/TypeTools.html#toString) and it remains to be determined whether that is a reliable choice. Please report any issues you might face.
