Yes, because it has a default argument which it passes to the Appender
constructor. If only we had default constructors for structs in D.. or
a general solution to this issue. I remember maybe a year ago or so
I've ran into the same issue with hashes, and now it almost bit me
hard again (luckily this was caught immediately in a failing
unittest).
