@ArneBab I would like to make my current work on tests APIs to be SRFI as well, but IDK if I will be able to make it guile-agnostic.
Anyway, I'll keep in mind the idea of tests in procedure's metadata and will let you know if I do something like that or would be able to integrate your work. Thank you for ideas, knowledge and your support! :)
@abcdw An implementation for a SRFI does not have to be implementation agnostic, though that’s preferred.
The doctests here are the result of starting with Python-style doctests, then discussing that in the Guile list and finding this cleaner solution. Thanks to homoiconicity, we can write real code in the properties that then gets executed. This saves us from problems like the different quoting and multi-line stuff in Python-doctests.
