i think there are different intentions. the question is: what do you
want to express?

* iterate over a range of integers
* do something N times

boost.range is wonderful to express the first case! my proposal tries to
add expressive power for the second ...

again comparing this to ruby:
(0..9).each {|i| print i, "\n"}
10.times {|i| print i, "\n"}

or supercollider:
(0..9).do (_.postln) (_.postln)

one does not need to know these languages to see that the developer
wants to express different things ;)
