Following the local registry example at https://github.com/metosin/malli#local-registry calling (malli.core/schema? Adult) => false . This surprises me..

Is it not a schema? Why not?

it’s just data?

Ah, I see. I see it expects a Schema protocol.... and you can use m/schema to turn the data into a Schema entity

I think the m/schema? is not that useful, could be removed.

as most of the functions consume data, Schema or IntoSchema .

m/schema? is used in some fdef specs in gungnir
