You mean “can the given form be used as a Malli schema”, not “does the given form conform to an existing malli schema”, right?

AFAIK there isn't yet a self-describing meta-schema for malli schemas; the only way I've done this is indeed with try/catch on m/schema.

that's right @UEENNMX0T 🙂 thanks @UFTRLDZEW!

Schemas can define their schemas as schemas. The IntoSchema has the needed hooks, someone just needs to write the Schemas for properties & Children.
