Stay in the scheme sphere long enough everyone has their SRFI moment and one concerning SRFI-19 in particular. Here I refer to the, "that's it, I can't stand no more, by god, this time I'm going replace SRFI-19" moment.
A couple of months back I had my nth moment with SRFI-19 and my usual partial response. https://github.com/RayRacine/racketlib/tree/datetime/src/racket/datetime In SRFI-19's defense, unsurprisingly, the overall approach and design of SRFI-19 captures the gist of what needs to be done. That said, I did spend the rest of the morning cut and pasting a few core aspects of SRFI-19 around (core being those features I immediately needed). FWIW, I seem to recall the current Racket impl is missing a couple of leap second adjustments in the current release. Overall I agree a number of SRFIs should be tidied up a bit, ported to modernized Racket syntax and added as part of the standard Racket collections. But who has the time?
