This is kind of funny. This works because reduce is defined as follows:<br>
<br>
template reduce(alias fun)<br>
{<br>
alias Reduce!(fun).reduce reduce;<br>
}<br>
<br>
I did that to work around some old compiler bugs that have been since fixed. I'd initially intended to define reduce like this:<br>
<br>
Unqual!E reduce(alias fun, E, R)(E seed, R r) { ... }<br>
<br>
but that wouldn't have allowed Nick's alias, which is quite useful. So it looks like we have a cool idiom.</blockquote><div><br></div><div>Currying in general is always handy to have. The possibility to say </div>
