   Identifier? is part of the low-level macro system described in the
   appendix to the r4rs.  As far as I know, this system is not
   implemented on any commonly used scheme system.

This is right.  But perhaps it was `symbol?' that the original poster
was looking for.  `symbol?' should be available in all implementations
which claim to be R4RS conforming.
