I’ve been looking at some sample code from th eFlux model zoo, and I came across something like: f(x) = x^2 d = (f(i) for i in 1:10) (this is much simplified to help pose the question). The result indicates that d is Base.Generator{UnitRange{Int64},typeof(f)}(f, 1:10) - I cannot find any document…

The idea behind a generator is that it can produce it’s elements one at a time without allocating storage for all of them. You could for example, write 'for x in d` and your will iterate over the parts without having to allocate. This is very useful if the list certain would be really large.

What is a Base.Generator?

I can try again later - I typed in generator and then did a search in the resulting web page for Generator and never found it
