Those are all fairly common things to do from inside the 'dg' call.
The int is how the compiler distinguishes which case got you out of
the dg.

You didn't read my post carefully.
The use case you would lose is:
int opApply (int delegate(something) dg)
{
auto result = dg(stuff);
if (result)
{
// This would be impossible if we took a void delegate.
log ("iteration stopped early");
return result;
}
return 0;
}
Why would you ever want to do that??
