> There was a thread on the Rust reddit where someone was asking how to do something relatively simple using some elaborate combination of map/reduce/filter/continuations/who-knows-what, and someone said "just use a for loop", and the OP was enlightened.

I think it's hard to discern between "that overly-complex functional and declarative definition is unfamiliar to me" and "that is way over-complicated and should just use a for loop".

Any chance you can track down that example so others can compare the two examples as well?
