Bizzare import interaction resulting in attempting to call undeclared routine: 'toJson'.

[dawdmaow]

This is probably a compiler error, but I wasn't able to come up with a reproduction without jsony.

Nim version: 2.2.0
Backend: c

imported.nim

import pkg/jsony

type
  Foo* = ref object
    foo: float # Remove this line and everything works 🤡

proc serialize*(msg: Foo|float) =
  discard toJson(msg)

main.nim

import imported
# import jsony # Add this line and everything works 🤡

serialize(Foo())

Output
