I implemented something like this and also display spec messages in console. But i’m using https://github.com/metosin/malli. What do you think to have something like helix.malli

ship it!

I think these are not things I would want in the main helix library, but are great as addons from the community

I totally agree with it. I need to polish some things before open sourcing it. Will try to find time on it
