I take a look a bit, I found that your `return_type` is `Union`, but If I understand correctly, you should compute the return type based on args. For example, your test `json_get(json_data, 'foo')`, if you compute the return_type based on `foo`, you return `Int`, then you will not meet the error. The error is because Union is not yet supported in `comparison_coercion` -- This is an automated message from the Apache Git Service.
