Scheme Request for Implementation 165,
"The Environment Monad,"
by Marc Nieper-Wißkirchen,
has gone into "final" status.

The document and an archive of the
discussion are available at
<https://srfi.schemers.org/srfi-165/>.

Here's the abstract:

  Monads model computations.  The
  environment monad models computations
  that depend on values from a shared
  environment.  These computations can
  read values from the environment, pass
  values to subsequent computations,
  execute sub-computations in an
  extended environment, and modify the
  environment for future computations.

Many thanks to the author and to
everyone who contributed to the
discussion of this SRFI.

Regards,

SRFI Editor
