Cyclic load dependency in babashka

[lilactown]

When using grasp with babashka, requiring the grasp.api namespace fails with the message Cyclic load dependency: grasp.api->[ grasp.impl ]->[ grasp.impl ] [at grasp/impl.clj]

I'm not sure why grasp.impl requires itself. I get other errors when I remove it, which I'll open other issues for when I investigate further.

Minimal reproduction

$ echo '{:deps {io.github.borkdude/grasp {:mvn/version "0.0.3"} org.babashka/spec.alpha {:git/url "https://github.com/babashka/spec.alpha" :git/sha "8df0712896f596680da7a32ae44bb000b7e45e68"}}}' > bb.edn
$ bb
Babashka v0.9.161 REPL.
Use :repl/quit or :repl/exit to quit the REPL.
Clojure rocks, Bash reaches.

grasp currently doesn't work in bb, but you can use the grasp binary. PR welcome to remove the self-require. I've noticed that Clojure is accepting of this, perhaps SCI should also accept this.

I hit this issue as well, when attempting to load grasp into a REPL started using rules_clojure. Tools.namespace does not accept circular references
