Hi,
I've been reading Clojure sources in order to get a better understanding of
how and why things work and found this implementation of nth function
in src/clj/clojure/gvec.clj:
(nth [this i not-found]
(let [z (int 0)]
(if (and (>= i z) (< i (.count this)))
(.nth this i)
not-found)))
The question might sound weird, but anyway.. Is there any reason for doing
so instead of:
(nth [this i not-found]
(if (and (>= i 0) (< i (.count this)))
(.nth this i)
not-found))
or is it just a matter of taste? I'm just curious because the first form seems
more verbose and doesn't improve readability, though it's not complex either.
Thanks.
