Not really. Generator basically gives you external iterators which you
can access element by element, so you can do things like iterate over 2
enumerables in step. What I wrote is basically just a convenience for
applying a method call to all the elements in a single enumerable.
After all,

  %w{a long list of words}.collect.length

is the same thing as

  %w{a long list of words}.collect { |item| item.length}

but easier to read.

Ok, then I'll probably package it up tomorrow.
