Implement IFn protocol for matcher
(lif cond-pattern then-pattern else-pattern) else-pattern is optional "IF data matches with cond-pattern (result of match is not empty) THEN use result as a preconditions for match then-pattern against the same data ELSE match the data against else-pattern if present."
takes a function of one argument and pattern. Before match agains some
data will apply this tr-fn function to the data before applying pattern.
```
(matches (reshape-by (juxt ex-message ex-data) ['?msg {:type :input-error}])
(ex-info "Message" {:type :input-error}))
;; => '({?msg "Message})
```
Same as clojure.core/destructure
```
[?x ?y & [?x ?y ?z]]
[1 2 1 2 3]
;; => {?x 1 ?y 2 ?z 3}
```
