Type instability in Folds.map #55

Hi,

I recently posted an issue (see here) on the Julia discourse regarding Folds.jl. Reposting here for visibility.

I’ve noticed that the Folds version of map() seems to introduce type instability:

using Folds
f1(K::Integer) = map(identity, 1:K) 
f2(K::Integer) = Folds.map(identity, 1:K) 

@code_warntype f1(5)
@code_warntype f2(5)

Do you have any suggestions for how to address this? Thanks in advance.
