The idea is to make it easy to build procedures that extend Guile’s read
procedure.  Readers supporting various syntax variants can easily be written,
possibly by re-using existing “token readers” of a standard Scheme
readers.  For example, it is used to implement Skribilo’s R5RS-derived
document syntax.

Guile-Reader’s approach is similar to Common Lisp’s “read table”, but
hopefully more powerful and flexible (for instance, one may instantiate as
many readers as needed).")
