The field names and order in the constructor will always match the
values specified in deftype (excepting certain character issues, such
as turning a dash into an underscore).
Introspecting is easy enough:
user=> (deftype foo [bar baz])
user.foo
user=> (map #(.getName %) (.getDeclaredFields foo))
("bar" "baz")
Though defrecord emits quite a few more fields beyond what was
specified.
