Please always compare to the matching DMD version, 2.074.1 in
this case, which produces an empty string as well, I guess
because the writer was taken by value in Phobos 2.074.1.
Fair point on the DMD versioning. I think I was only using the
most recent DMD. I had thought this capability was added in
2.074.0 when the CT string feature was added, but the changelogs
only reference formattedRead, not formattedWrite.
I don't know when it was actually added.
