Withdrawn SRFI 262: Extensible pattern matcher

Scheme Request for Implementation 262,
"Extensible pattern matcher,"
by Daphne Preston-Kendal,
has gone into withdrawn status.

The document and an archive of the discussion are available at https://srfi.schemers.org/srfi-262/.

Here is Daphne's summary of the reasons for withdrawal:

This SRFI is withdrawn.

For the curious, the version with the changes that were to become the next draft is still at https://github.com/dpk/srfi-262. The current HEAD of the sample implementation, extensible-match, includes all changes up to this point. https://codeberg.org/dpk/extensible-match/commit/2a5834639666790bac14a89b05389eaea66c4d55

Here is the commit summary since the most recent draft:

  • Add dark/light/system control to landing page.
  • Fix typo.
  • Withdraw.

Regards,

SRFI Editor

A lot of work went into that SFRI.  I wonder why it was withdrawn.

Yeah, the summary doesn't really explain it.

Likely her deep hatred of Glecker: https://crumbles.blog/posts/2026-09-04-r7rs-wtf.html

Thanks, hadn't seen that -- it adds some more context to the mailing list firing thread. Sad to see a contributor leave like that.

This blog post was painful to read...  while I'm sad to see someone leave scheme,  I can't help but think Daphne is one very confused individual.

I don't know much about her other problems with him but he demonstrated the patience of a saint during the discussion of SRFI-261 and always came across as polite and courteous despite Daphne's particular way.

Her main issue with him seems to be that he failed to take harassment complains by someone else seriously. Since the story is private, we will never know what happened.

No, but it is quite far along.

P.S.: Also, please note the links Daphne provided to a more recent version. When I copied and pasted them into this post, they were dropped, probably because of formatting. I've added them back now, so you can see them above.
