So somewhere in the last 162 commits, this got caught. Probably r52914, but it
looks like it hasn't been recored in NEWS (and it should be as this was
apparently a live bug, not an obscure corner case):

Modified applydefine to duplicate if necessary to ensure that the
assignment target in calls to assignment functions via the complex
assignment mechanism always has NAMED == 1.
Yes, that was the one. It was reported as a bug back then too, and
there was quite a bit of discussion that ended up with Luke's fix.
There is also a bug fix to that fix a few days later.
