> Can you elaborate with an example for s/valid? on needing to preconfrom your data. I have not had this issue.

If you have any conformers, s/valid? will use them before validating.

So, if you have a 'set' conformer, for example, s/valid? will tell you that the data is valid even if the value is not a set, but a vector, for example.

Your code must explicitly call 'conform', checking with s/valid? is not enough.
