This is a well known issue, we have to define types and not mix them due to implied type inference, this is sort of a feature and not a bug as type inference is preventing verification. I will see what we can do to alert the user Em sáb., 1 de fev. de 2025 07:38, Lucas C. Cordeiro < ***@***.***> escreveu:
