@aman-goel can you please help here?

[aman-goel]

Hi @PoorlyDefinedBehaviour . Thanks for trying out PSym! PSym currently does not support type-casting with the any data type. Try changing var count: map[any, int]; to var count: map[int, int];.

Hi @PoorlyDefinedBehaviour . Thanks for trying out PSym! PSym currently does not support type-casting with the any data type. Try changing var count: map[any, int]; to var count: map[int, int];.

I see, would it make sense to improve the error message a little bit?

[ankushdesai]

We are planning to drop the support for PSym.
