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).")

A transition table can be verified and checked for dead-ends and infinite

Guile-SMC comes with a Scheme program called @command{smc} -- a state machine

with a FSM is being built (for example, from a Makefile.)")
