Neat trick! :)
Conversion looks correct.
Two nitpicks are:
1. It's not really a factory, but I guess we can give it an unusual name
in our world so it sticks out as unusual.
2. We could simplify by avoiding macro tricks by just passing in {
.field = value } by value.
I don't actually mind the trick, but since it is a novel concept in IGT
codebase (AFAIR), then please run it past Petri at least.
