Hi all,
clojure.spec helped me realise that NaNs totally break [1] equality (per
`clojure.core/=`). Even though in real production code this might not be
an issue due to how infrequently one deals with NaNs, but during
gen-testing I've found them extremely annoying, and I've essentially
worked around this by spec-ing things I'd normally specify via `any?`,
via `(s/and any? (complement double-NaN?))` instead. I have to do this
for any spec, where in the :ret spec i need to be able to confirm that
the input coll is equal to the output coll (e.g. `clojure.core/remove`
returns the same coll it was passed in when nothing has been removed),
which is a possibility in a lot of functions. Have other people
encountered this as well, and if yes, how are you guys dealing with it?
Thanks in advance...
Kind regards,
Dimitris
