Overall the patch looks good to me.

One question: We usually avoid packaging software that has no release or
has an “alpha” or “beta” label.  Do you think we could wait for 1.1.0 to
be officially released?  Or are there good reasons why we should not
wait?

Some minor issues:

Could you add a comment explaining why the previous version of these is
needed, instead of the current version?

> --- /dev/null
> +++ b/gnu/packages/patches/ldc1.1.0-disable-dmd-tests.patch

Could you add a line or two explaining at the top of patch explaining
what it does and why, and what its upstream status is?

For example, I think this one disables a test that would require GDB,
which is not an input (?), and presumably it won’t be submitted
upstream.

I think it’s better to just delete the two lines instead of commenting
them out: that makes the patch easier to read.

Hope this makes sense.

Thanks for your contribution!
