@abcdw @luis_felipe The number of times I saw some library or standard library thing in the Guile ecosystem and thought: "Oh that exists?!" … Always a pleasant surprise to find something awesome, but sometimes one wishes, one had found things earlier.

Like for example when I tried my hand at implementing function contracts and then it turned out, that there is already a port of how Racket does it for Guile …

Or recently I found guile-filesystem.
