Thanks for this patch!

Overall looks good, but the hash of the source code is not correct for
me:

------
r:sha256 hash mismatch for /gnu/store/f4gz64dfsqmhbbg24ggzf9ffcr6k2znf-guile-websocket-0.1-checkout:
  expected hash: 10r8384frlyrljjdyzilrh8hzi60v9hisx4fxjs7rmg9g01cs77k
  actual hash:   1hymvsfrmq9qxr5cxnsgdz7y757yp1cpsgxmdp3f5wxxxpqgsmzx
hash mismatch for store item '/gnu/store/f4gz64dfsqmhbbg24ggzf9ffcr6k2znf-guile-websocket-0.1-checkout'
build of /gnu/store/n6kxplhzysqq4d82p1m2wa2y48lbgswb-guile-websocket-0.1-checkout.drv failed
------

My guess is that you already had something corresponding to the expected
hash in /gnu/store, and so Guix did not even try to clone the upstream
repo. Probably another commit of guile-websocket, assuming the package
did build for you.

Can you take a look and send a revised patch?
