Final SRFI 151: Bitwise Operations Arthur A. Gleckler 10 Jul 2017 19:36 UTC

Scheme Request for Implementation 151,
"Bitwise Operations,"
by John Cowan,
has gone into "final" status.

The document and an archive of the discussion are available at <>.

Here's the first paragraph of the abstract:

  This SRFI proposes a coherent and comprehensive set of
  procedures for performing bitwise logical operations on
  integers; it is accompanied by a reference implementation
  of the spec in terms of a set of seven core operators.
  The sample implementation is portable, as efficient as
  practical with pure Scheme arithmetic (it is much more
  efficient to replace the core operators with C or assembly
  language if possible), and open source.
