Indeed, see
https://github.com/dlang/phobos/blob/cd2ba0d2c378a893ec0eaefc57b87d0770a1990c/std/bitmanip.d#L293-L314
It doesn't necessarily need to be in a unittest block (AFAIK,
the example executer isn't actually running the unittests of
phobos), but it does need to be inside a function, because you
have executable code there. Either way, yes, it's run inside a
function, so you need to apply static to the struct to avoid
the frame pointer. I tested that, and it prints 1 instead of 16.

My reasoning was that a unittest is essentially a function and
it's incredibly convenient for such things but I hadn't really
checked prior to MoonlightSentinel's reply.
Thanks again :)
