Yes, I can see that. rx certainly has advantages. But it has
disadvantages too, which Mattias appears not to want to admit exist. To
be honest, I suspect the differences in readability/maintainability
between the two forms will be small. Maintaining Emacs, it is most
helpful to have at least a reading competence with both forms.
