fishy gen* call in your Spec protocol

[darwin]

I think I hit something which is expected to work and is broken.

Please consider this gist:

You can repro it on your machine with:

clojure -Srepro -Sdeps '{:deps {issue {:git/url "https://gist.github.com/darwin/e7748419304915f75633666b906f23f8" :sha "af929e906525703509a4f86ba371d74f8338dc71"}}}' -m main

The problem is that generating metosin-spec throws and it should work out-of-the-box in my opinion. I was able to track it down to this line, which seems to be problematic. It looks to me that you are trying to implement gen* by doing the work yourself and if that's not possible falling back to standard implementation. The problem is that you are passing your naked spec data structure which was provided by user. It looks like standard gen* implementation expects massaged spec by first applying specize on it. The difference is subtle but it breaks because of it in my case.

Please look at gensub helper which is doing that before calling gen* protocol:

I'm not saying this is the exact issue. I'm new to spec and don't have deep understanding here. Maybe @puredanger could shed some light.

Thanks for reporting. I think it's fixed now, see #138.
