Strict pattern matching mode

[thenonameguy]

It would be great to have an m/find! macro, which keeps the interface of the bang-less one, but instead of returning nil when the passed in value does not match the pattern it returns an exception/error object that contains why the match failed.
This would alleviate the current pain of finding the missing/wrong part of the input, without having to re-encode the expected structure in Malli/clojure.spec, etc.

The first half can be implemented as

(defmacro find! [& rules]
  `(m/find ~@rules _otherwise# (throw (ex-info "Non-exhaustive pattern match" {})))

The second part, however, is not something epsilon was designed for but is planned for zeta (which is still in development).
