   You should.  There is no good justification whatsoever for further
   propagating the shameful state of Scheme's error reporting semantics.

I agree with Shriram on this issue generally, but not in this
particular case.  SRFI-10 says nothing about what #,(<tag> ...)
means for any <tag>, so there isn't much point in saying what it
means for `undefined' tags.  With no defined tags and no way
of creating any, what does it mean to say a tag is undefined?
