facility, inspired by systems like Concurrent ML, Go, and Erlang.  A fiber is
like a \"goroutine\" from the Go language: a lightweight thread-like
abstraction.  Systems built with Fibers can scale up to millions of concurrent
fibers, tens of thousands of concurrent socket connections, and many parallel
cores.  The Fibers library also provides Concurrent ML-like channels for
communication between fibers.

Note that Fibers makes use of some Guile 2.1/2.2-specific features and
is not available for Guile 2.0.")

The idea is to make it easy to build procedures that extend Guile’s read

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).")

describes @code{curried}, a variant of @code{lambda} that creates true curried
procedures which also behave just like ordinary Scheme procedures.  They can
be applied to their arguments one by one, all at once, or anywhere in between,
without any novel syntax.  @code{curried} also supports nullary and variadic
procedures, and procedures created with it have predictable behavior when
applied to surplus arguments.")

escaping and thus can be written and read verbatim.

A transition table can be verified and checked for dead-ends and infinite
loops.  Also Guile-SMC FSMs gather statistics when they run.

Guile-SMC comes with a Scheme program called @command{smc} -- a state machine
compiler itself.  It produces a Scheme code for an FSM from the PlantUML
format.  This tool is meant to be called on a PlantUML file when a program
with a FSM is being built (for example, from a Makefile.)")

     "@code{guile-goblins} is the Guile version of
@url{https://spritely.institute/goblins, Spritely Goblins}, a transactional,
distributed programming environment following object capability security
designs.  Goblins is a general toolkit, and also the core layer of Spritely's
work to support healthy distributed networked communities.  Goblins allows for
cooperation between networked programs in a mutually suspicious network
through OCapN, the Object Capability Network.  This includes collaboration
across runtimes; for instance, programs written in the Guile and Racket
versions of Goblins are able to speak to each other.")
