Thanks for the advice. I think I have it now.
Problem:
A function F accepts a pair of stl-style iterators as input. A nullary
functor G can generate an output. Arrange for F to call G n times without
storing to an intermediate sequence.
Example: G is a random number generator.
I wonder if there is a more elegant approach? Here is what I came up with.
It is almost perfect, there seems to be 1 extra call to G() that I haven't
accounted for, but this may or may not be important.
