Here be the problem. I guess the solution is to make hasMember work w/ pointers to structs.<br><br>// In std.traits:<br>template hasMember(T, string name)<br>{<br> static if (is(T == struct) || is(T == class))<br> {<br>
enum bool hasMember =<br> staticIndexOf!(name, __traits(allMembers, T)) != -1;<br> }<br> else<br> {<br> enum bool hasMember = false;<br> }<br>}<br><br>This is never true for a pointer. isOutputRange checks whether put() compiles. The free function put() checks for having a put() member, which fails for pointers to structs.<br>

I noticed the difference of isOutputRange behavior.<br>

<br>
Pointer version of isOutputRange returns false on 2.048 and 2.049beta.<br>
I did't find the related changelog. Is this a bug?<br>
