The Revised⁷ Report on the Algorithmic Language Scheme - Daphne Preston-Kendal

(EDIT 20/08/2023: The current status of the project as outlined in this academic talk is, as of now, outdated)
Scheme is a small but influential dialect of the Lisp programming language which has been standardized in multiple more-or-less compatible versions since its creation in the late 1970s. After decades of being used almost exclusively in teaching and research (with some exceptions), Scheme is now in the throes of a second attempt to expand the standard language to make it practical for use in production environments, R7RS. This talk will give a brief overview of the history of Scheme standardization over the last five decades, compare the initial ‘small’ version of R7RS (intended to carry on the tradition of versions of Scheme intended for use in teaching, research, and embedded environments) to previous standard versions of Scheme and assess its success so far, and review current progress on the ‘Large’ version of the standard (which is intended to be practical for developing large, real-world applications) and the difficulties of standardizing a practical but usable version of ‘the world's most unportable programming language’.

28:50 That was a superb explanation of the concept of hygienic macros and the various solutions to the problem.

This video was awesome! I've been getting into Racket and thought I'd see what's going on with R7RS. Did not expect such a good introduction into the history of Scheme.

Thanks so much for this!

Great video i hope after a while guile moves to r7rs but I fucking love guile

BAD! i cannot listen it calmly -the pronunciation of Daphne Preston-Kendal is just terrible.
i have a speech defect myself [i cannot pronounce "l" because i have a mutilation], but i do not pretend on giving any lectures.
the subject is just great, she is just not confident or maybe is unprepared to the talk.
cannot listen to this syncopation babbling

You could have expressed your feedback without resorting to insults like "syncopation babbling".

Funny you feel this way. I’m French, thus English isn’t my mother tongue and I understood every word without difficulty. I guess our individual differences have little to do with the speaker herself.
