Is there a LDC that incorporates the changes coming in DMD 2.068 that made
my code run 10x faster compared with 2.067? (the one Andrei talked about in
the StackOverflow-link given earlier in this thread:
https://github.com/D-Programming-Language/phobos/pull/3089 ).

I have tried "ldc2-0.15.2-beta1-osx-x86_64" and also built LDC from the
Git-archive sources. In both cases I get times around 13s. This is close to
my original "bad" numbers from DMD 2.067 (15s).

I assume I have to wait until there is a LDC using the same Phobos version
as DMD 2.068 uses.
