+> The first could be solved (if you care) by a syntax like this:

+> meta_defaults => [

+> The second could perhaps be solved by invoking `meta::preprocess` from within
+> `scan` (which might be a simplification anyway), although this is complicated
+> by the fact that some (but not all!) meta headers are idempotent.
