+@yglukhov After thinking, I decided to take the time to implement the entire
+JWT standard (RFCs 7515-7520). This ended up being a pretty big architectural
+change.
+
+The result of my effort currently lives here:
+https://git.jdb-software.com/jdb/nim-jwt
+
+I'd love to get feedback on the implementation and thoughts on how this fits
+into the Nim ecosystem: does it make sense to have parallel implementations,
+naming, etc. For broader discussion I opened a thread on the Nim forums:
