Some interesting and fruitful conversations, thanks for uploading

I had a quick go to see if I could put together a fpm package for stdlib, you can see the result here:
Instead of a tarball (unsupported in fpm currently), it’s simply a separate repo which is generated automatically by the CI.
Needs a bit of testing, but the included tests run (on Ubuntu) and it seems to work okay as a fpm dependency.
For me at least, this overcomes a small hurdle to playing around with stdlib by simplifying the build procedure.
