Do people tend to use fold in a way where the accumulator variable is a hash or has multiple values?

@slack1 not typically, but it’s not unheard of

for/fold is somewhat more common for that

Nuuu hehe

I am waiting for that one to update

I hear it will update soon

fwiw, for/fold (the existing version) is still strictly more powerful than foldl / foldr

so I’m not sure what you mean by “waiting for it to update”

I don’t want to return multiple values on the last iteration

since it’s hard to handle multiple values in general

foldl and foldr don’t support multi-valued accumulators

but you can just use a list as a tuple

I mean for/fold and something like #:finally

Otherwise I have to return multiple values, am I wrong?

ah right that #:return keyword or whatever it is

#:result

you do have to return multiple values, but you could just ignore the values you don’t care about

You mean like in a let-values?

yes

mm thanks I shall try it out
