Records delegate their clojure.lang interface methods to the map fns

Browse source 
A defrecord is Associative/ILookup/IPersistentMap/Seqable/Counted on the JVM,
so (.assoc r k v) / (.valAt r k) / (.without r k) / (.containsKey r k) /
(.cons r x) / (.count r) / (.seq r) / (.equiv r o) / (.entryAt r k) now work
via Java interop, delegating to the map fns when not overridden by a declared
method. reitit's impl calls (.assoc match k v) directly. A bare deftype uses
its own declared methods (record-only branch). reitit-core 58/1/18 -> 321/1/1
with the router lib's Trie shim.
