Changes:

• Introduce clojure.core-test.repeatedly with tests for laziness, side effects, arity behavior, and error cases.
• Gate the suite behind when-var-exists for portability across runtimes.

Overall, looks good.

Hm, I just went to https://cljs.io/ and tried 1/3 and it gave 0.333333. I then cross-referenced that with the differences from Clojure doc which says Ratio isn't supported.

So I used this to see that CLJS supports reading ratios, but doesn't have a ratio object and instead just reads them into floats.

When I ran it on the test suite locally I got an exception so I think the local CLJS we're using doesn't support it

Okie dokie! Let's not worry about it for now then.

Maybe shoot a quick Slack message out to #cljs-dev.
