Yes.

I'm trying to think how this would be useful. Would you want to
test with different values than T.init? Or is there some
library that can generate random values based on a type?
What about user defined types? T.init my not be useful at all.
I don't want to sound negative but I'm trying to see the use
cases.
There's this: https://github.com/mcandre/dashcheck
Didn't Robert have a QuickCheck-alike as well?
Like I said, I'm not sure of the use cases, but I thought I'd
enable it and it was fun to do. I know I've written template unit
tests in C++ in the past, but I can't remember why.

Do you have a slightly more extended example that shows how
this is used?

It is not clear that this UDA is about unittesting
Even when attached to a test function?
