A draft of a proposed GNU extension to the Algol 68 programming language has been published today at https://algol68-lang.org/docs/GNU68-2025-004-supper.pdf.

SUPPER stropping in Algol 68 This new stropping regime aims to be more appealing to contemporary programmers, and also more convenient to be used in today's computing systems, while at the same time retaining the full expressive power of a stropped language and being 100% backwards compatible as a super-extension.

The stropping regime has been already implemented in the https://gcc.gnu.org/wiki/Algol68FrontEndGCC Algol 68 front-end and also in the Emacs a68-mode that provides full automatic indentation and syntax highlighting.

The sources of the godcc program have been already transitioned to the new regime, and the result is quite satisfactory. Check it out!

Comments and suggestions for the draft are very welcome, and would help to move the draft forward to a final state. Please send them to algol68@gcc.gnu.org.

Salud, and happy Easter everyone!
