 :!: This doesn't work with private methods, since you can't have private abstract methods, and hence you need to implement a dummy body on those ones.
+If a method requires a return type, it is conventional to throw an ''AssertionError'' as the content is never executed.

+:!: Disabling remapping on an annotation causes the internal remapper to skip the annotation entirely, thus, if the ''@Inject'' does not need remapping but the ''@At'' does, remapping must be explicitly re-enabled in the ''@At'' via ''remap=true''. Mixin can tell the difference between an annotation attribute being set or whether it uses the default.
 :!: Changing the remap setting may not fix an issue that would apparently seem to be remapping related, however, so it is best to seek direct support for your specific case.
