with the following functions:

</p><pre class="programlisting">

power (x, n);

power (x, n, moniod_operation);</pre><p>Returns, in FORTRAN syntax, "x ** n" where n>=0. In the

case of n == 0, returns the identity element for the

monoid operation. The two-argument signature uses multiplication (for

a true "power" implementation), but addition is supported as well.

The operation functor must be associative.

</p><p>The <code class="code">iota</code> function wins the award for Extension With the

Coolest Name. It "assigns sequentially increasing values to a range.
|

That is, it assigns value to *first, value + 1 to *(first + 1) and so
|
||
on." Quoted from SGI documentation.
