I am looking for the recommended way to “drop” the shape property of an iterator. Eg for itr = Iterators.product(1:5, 1:2) I want itr_flat such that collect(itr_flat) == vec(collect(itr)) without, of course, collecting it first. It is relatively straightforward to implement a wrapper that does …

Thanks for both answers. They are nice workarounds, but I think that something like an Iterators.vec would convey semantics better. I will make a PR. EDIT Silly me, there is IterTools.ivec .

Another hack is to use comprehension with if true clause

itr = Iterators.product(1:5, 1:2)
itr_flat = (x for x in itr if true)
collect(itr_flat) == vec(collect(itr))
