(type record) returns its class-name string, not a symbol

Browse source 
(type r) returned a symbol user.TyR, so (= (symbol (str (type r))) (type r))
was true; the JVM's type is a Class (not a Symbol) so it's false. jolt models
classes as strings, so a record's type is now its ns-qualified class-name
string — equal to (class r), as on the JVM where type and class coincide for a
record. The symbol-keyed print-method defmethods already fall through to the
default record printing, so they're unaffected. Closes type-of-record.
