Easy way to attach custom errors to schemas

[ikitommi]

Maybe lift the ErrorSchema protocol from malli.error to malli.core to enable setting the custom errors like this:

(m/-simple-schema {:type :symbol, :pred symbol?, :error/message {:en "should be symbol"}}})

[ikitommi]

This will be fixed in #255 .

[ikitommi]

(-> (m/-simple-schema
      {:type :symbol
       :pred symbol?
       :type-properties {:error/message {:en "should be symbol"}}})
    (m/explain "invalid")
    (me/humanize))
; => ["should be symbol"]
