R7RS Initial Results of Implementor Intentions Poll

The following all intend to support R7RS small:

  • Per Bothner (Kawa)
  • Will Clinger (Larceny)
  • Shiro Kawai (Gauche)
  • Manuel Serrano (Bigloo) – “not sure about libraries”
  • Alex Shinn (Chibi) – “already fully implemented, but lacking tests”
  • Felix Winkelmann (Chicken)

The following were less committal, but open, and their implementations are flexible enough to implement R7RS in third-party code:

  • Kent Dybvig (Chez) – “if it’s as simple as you say I don’t see why not”
  • Matthew Flatt (Racket) – “if there’s sufficient user demand”
  • Andy Wingo (Guile) – “probably”

The following are simply unable to implement R7RS or uninterested in standards:

  • Taylor Campbell (MIT) – “MIT lacks the infrastructure for modules”
  • Jonathan Shapiro (TinyScheme) – thinks call/cc should be removed
  • Jeffery Mark Siskind (Stalin) – “no longer working on Stalin”
  • Michael Sperber (Scheme48) – “no time even for R6RS”

No one refused to implement based on the content of the standard, or cited any features as showstoppers.

That last part is important; R6RS didn’t have that quality.
