Yes, mostly this idiom is for working on iterators, rather than
tables, and many of those iterators will represent input from a file
or a socket, etc.  Such data is potentially unbounded, multi-valued
and not fully accessible at any given instant, so is more general than
the table/array concept.

The performance of using iterator chains with such data would probably
be dominated by i/o.

PS. I do still believe in for-loops. But life could be clearer without
so many of them.
