@ikitommi I haven't looked at the code at all yet, but how difficult do you think it would be to extend the malli.provider to be pluggable / use transformers? ie. Ideally I could specify a transformer and it'd try transformations in there, and it'd check types that exist in the registry when called

Looking at the code - doesn't look like it'd be too hard to make it take a transformer!

The only thing would be handling the fact that multiple transformers could pass and then having to keep track of which one was most successful

But we are kinda already doing that with the type anyway
