If a reader returns sexps, then the only way to add location info is via
source properties.  I think it’s OK to use that throughout the code.
The outline and RSS readers don’t do that but they should.

In Guile 3.0.8, ‘read-syntax’ returns location info directly in syntax
objects, but I’m not sure Skribilo readers should return syntax objects,
that sounds inconvenient.

HTH!
