Thank you, John!  I would like to see your Chicken implementation
included in the SRFI 229 repository.

Note that you could also have `procedure/tag?` return `#t` in all
cases, which is probably better than exploiting the "is an error"
condition.  See the documentation of the two procedures in section
4.3.
