Thanks!

It would be even greater if the GC could automatically do

   -DRT-gcopt=cleanup:none

automatically for all the GC-allocations of aggregate types that don't have a destructor (hasElaborateDestructor being true for structs and classes).

Would that be possible to implement?

I presume that would require segregating the heap even further, right?

Correction:

These objects would still have to be scanned, so there is not much that could be saved with respect to performance.

BTW: DRT options have a double-dash at the start, e.g.

--DRT-gcopt=cleanup:none

This should be corrected in the blog post, too.

Thanks for the tip, but it was on deployment on clean machines so everything is downloaded from scratch. No caches as far as i could tell. Double checked on my machine as well and still the same.

I did however notice that it also works on 2.085.0 if i import it a different way:

i.e. this works:

void main() {
 	import ddash.functional: stringifySeperatedBy; // difference is in import statement
 	writeln([1, 2, 3].stringifySeperatedBy("."));
}

So I guess maybe dub is off somewhere, or something which shouldn't have been working was.

Was supposed to be fixed in this release.
