<div><div></div>When using your method, you have to use:<br></div>
----<br>
each!(array, typeof(array))((int item) {writefln("%d", item+b)});<br>
----<br>
(I believe this is a bug, dmd should be able to deduce the type here). </blockquote><div><br>OK. I suppose I'd do:<br><br>void each(alias array)(void delegate(ElementType!(typeof(array)) item)
dg) if (isArray!(typeof(array))) {<br>
foreach(T i; array)<br>
dg(i);<br>
}<br><br>and then:<br><br>each!([0,1,2,3])( <br> (int i) { writeln(i);}<br>);<br>

----<br>
void foo(int a) { writefln( "%d", a ); }<br>
/// Prints 1<br>
foo = 1;<br>
----<br>
I didn't realize this worked for free functions, apparently it does. I think in newer versions of D2 functions like this will have to be marked with @property, I don't think dmd currently enforces this though.<br>
</blockquote></div><br>Urgh. OK, I didn't think of properties, thanks a lot Robert ! <br>I think it explains some strange errors I have somewhere else, when trying to assign some value and getting strange unvalid args errors. DMD transforms my foo = something into foo(something).<br>
