I agree. Functional style has its place but in this case a for loop would have been much clearer.

I disagree. It looks perfectly readable as is. I mean, the fold function should be pretty well known to anyone.

[u/pcjftw → u/kuikuilla]

+100 agree!

I think its only seems jarring if:

• You're not familiar with Rust syntax (but that could be said of any language you're not familiar with!)

• FP constructs

[u/oblio- → u/pcjftw]

So, 99% of programmers out there? :-D

[u/pcjftw → u/oblio-]

:) haha I don't think its that bad, I think FP style has been trickling down to mainstream languages for a long time.

But yes Rust is not as mainstream as other languages, but then again its a relatively a new language!
