Is there a good reason, why last is not implemented for Generators? I came up with function Base.last(iter::Base.Generator) x = last(iter.iter) return iter.f(i) end which does exactly what I would expect (and also in O(1) time, like the default implementation of last(a) = a[end]. If this …

I believe that is because general iterators are not required to have finite length.

The discussion in the PR answers my question. Thanks!

Why no `last(::Generator)`?
