Records constructed with missing arguments look equal, but aren't

[dfrese]

When having an RTD-record, and two values of that type, one with argument 'nil', one without any:

(rec/define-record-type FileSource
  {:rtd-record? true}
  (make-file-source file) file-source?
  [file file-source-file])

(def v1 (make-file-source nil))
(def v2 (make-file-source))

then they look equal

(= (pr-str v1) (pr-str v2)

but, aren't

(not (= v1 v2))

which is very confusing. Would be ok to not be able to construct them with missing arguments, but otherwise they should be (=), I would expect.

I would say the result of this

(def v2 (make-file-source))

is undefined behaviour. In Clojure, this even throws an ArityException at runtime.

So, @dfrese can we close this issue?

[dfrese]

Yes, but only because it seems not to be like this anymore.
I get `wrong number of args" now.
