For many types of programmers that would be happy with something like C or Go, most likely yes, given that they already allow for some interesting patterns. Also because they changed a bit, in the early days you could not pass arguments back to them.

However, when I wrote generators I was actually thinking about comprehensions.

I think comprehensions are less advanced (they're a specialized case of iterators) and very commonly used.

Sending arguments is certainly advanced.
