In addition to what Maxime wrote, I’d like to comment on the less technical side of it. I think it’s important to keep the code consistent in terms of API usage. There are often many different ways to do the same thing in Guile and Scheme, but within Guix, settling on one (or two) ways for a given things is preferable: it makes it easier for us all to understand and maintain the code. There’s no widespread “Maybe” idiom in Scheme; or rather, people use TYPE | #f as a way to approximate “Maybe”. It’s not ideal, primarily because appropriate handling is not statically checked. Yet, that’s what we have and I’m not convinced adding SRFI-189 to the mix would bring enough of an improvement to justify it. Thoughts? Thanks, Ludo’.
