One question about
https://github.com/treeform/jsony#proc-parsehook-can-be-used-to-do-anything (and
how proc lookup works). I'm running into an issue where I've defined a custom
"parseHook" in one module, and now a different module I have (which doesn't
import the first one) is also attempting to use the same parseHook to parse
JSON, which breaks it. Is there a way to avoid this? I don't want the exported
proc in one module to affect a different module at all, especially when they
don't depend on each other.

Both are imported into the same `main` file though.
