SRFI Support
~~~~~~~~~~~~

The SRFIs (Scheme Requests For Implementations) is an Internet-based
collection of Scheme code designed and provided by Scheme
programmers. The SRFI effort is open to anyone, and is described at
http://srfi.schemers.org[].

The fundamental SRFI is SRFI-0, "Feature-based conditional expansion
construct", which allows a program to query the underlying
implementation about the available SRFIs (and potentially about other
implementation features) at macro expansion time. The design documents
for this and other SRFIs are available at the web site shown above.

Larceny currently supports many SRFIs, but not as many as it should.
Some SRFIs are built into Larceny, but most must be loaded dynamically
using Larceny's `require` procedure:

    > (require 'srfi-0)

Larceny provides the following nonstandard SRFI keys for use in
SRFI 0:
