The example code you posted most definitely should not compile because S is not
iterable. I guess you forgot the opApply() or range primitives. The following
code *does* compile successfully:
import std.traits;
struct OpApply
{
@disable this(this);
int opApply(int delegate(ref uint) dg) { assert(0); }
}
struct Range
{
@disable this(this);
@property uint front() { assert(0); }
void popFront() { assert(0); }
enum bool empty = false;
}
static assert (isIterable!OpApply);
static assert (isIterable!Range);
