 Perhaps that's it. I only aliased it to save on typing in this large block (some
200 entries). Easy work around since the structure is never used elsewhere (and
instantiated immutable); So I converted my char[4] to immutable(char[4]) and the
problem went away. But knowing it will be immutable later, it seems like it should
figure it out.

 This is one of those lesser details they will get to later. I am not going to
pester them, unless you think I should enter a bug report.
